COMMONGROUND

Commonground is PS21’s annual free festival of large-scale contemporary performance and spectacle. A family-friendly celebration of the end of summer, Commonground welcomes the community to PS21 for performances from renowned international artists across the PS21 landscape.

This year’s festival takes place September 4–7, and features the world premiere of SUPERDRUM X, a work featuring 100 self-playing drums by Dutch musical collective Touki Delphine accompanied by a different live drummer each night. Plus: the world premiere of FIELD, a new PS21-commissioned performance by OBIE award-winning director, writer, and electronics artist Andrew Schneider, that gently removes reality from its normal and turns it inside out. Sayer Mansfield’s DIVE BARN showcase of local artists rounds out the lineup.

Each day, we’ll have activities on the lawn for the family leading up the performances, including West African food from Chez Diarra, free ice cream, apple picking, lawn games, and more.

ABOUT THE ARTISTS

Andrew Schneider is mostly interested in how humans telling stories about ourselves to each other can make us better at being humans. And how much the second law of thermodynamics and grief have in common. 

He is an OBIE award-winning, Drama Desk-nominated director, performer, writer, and interactive-electronics artist creating original works for theater, dance, sound, video, installation and public art since 2003.

Andrew’s work uses new and old, high and low tech – from Wave Field Synthesis arrays and Volumetric Lighting displays – to literal smoke and mirrors. He is interested in the edges of human perception, using science as a blueprint for staging, and above all, the question of – how does it make you feel?

Original works include HERE (2025 – Jacob’s Pillow) NOWISWHENWEARE (2022 – Brooklyn Academy of Music and ongoing tour); »remains« (2020 – Radialsystem, Berlin) commissioned by the Sasha Waltz & Guests Dance company; NERVOUS/SYSTEM (2018 – BAM Next Wave); AFTER (2018 – Under the Radar, The Public Theater); YOUARENOWHERE (2015 OBIE award, 2016 Drama Desk nom); DANCE/FIELD (2014 – Roulette); TIDAL (2013 – River to River); and WOW+FLUTTER (2010 – The Chocolate Factory Theater), among others. 

Andrew is/was a member of the ‘25/’26 Harvard Radcliffe Institute Fellowship, the Digital Future’s cohort at Jacob’s Pillow, Lincoln Center’s Collider cohort, the Doris Duke Foundation’s Performing Arts Technologies Lab inaugural cohort, the arts incubator ONX, was a Sundance “Art of the Practice” fellow, and has received a fellowship from the Junge Akademie / Akademie Der Künste in Berlin. He teaches a recurring class on original-flavor reality at the Interactive Telecommunications Program and mentors for Theater Mitu’s Hybrid Arts Lab. Wooster Group company member 2007-14.

Amsterdam-based Touki Delphine (Bo Koek, Rik Elstgeest, Chris Doyle and John van Oostrum) is a boundary-pushing collective of musicians, performers, and visual artists making waves nationally and internationally with their monumental light and sound installations made from recycled materials. Their work creates poetic encounters between humans and machines. Inspired by natural phenomena, the climate crisis and the idea of nature as a living whole, they explore how technology can not only alienate but also connect.

Touki Delphine is known for transforming discarded materials into powerful musical installations. In FIREBIRD, a unique orchestra of over 600 recycled taillights unleashes a hypnotic choreography of light and sound, transforming Stravinsky’s classic Firebird Suite into an otherworldly experience. In RELAY, 1848 turn signal relay motors create rhythm and harmony. In MACHINE, a second hand plant-potting machine is transformed into the drummer of an ensemble. For TRANSMISSION, miles of scrapped wiring and pneumatic tubing mimic an underground fungal network that hums and vibrates electrically. And DRIFTING, the breakout hit of the 2025 Dutch festival summer, is a new ecosystem built from nothing but waste: ethernet cables from thrift shops, windshield washer fluid reservoirs and their pump motors from junkyards, and salvaged speaker cables from Touki’s own studio. The piece comes alive in live sessions, where musicians engage in dialogue with the installation.

Sayer Mansfield is a dancer, performer, and choreographer based between the Hudson Valley and New York City. She spent over a decade touring the world with Compagnie Marie Chouinard (Montreal) and Pilobolus Dance Theater (NYC) and has since danced with The Metropolitan Opera, as a guest artist with the Mark Morris Dance Group, and in ongoing collaboration with Movement Museum/Marla Phelan.

Her screen work includes appearances in Little Women (dir. Greta Gerwig), Maestro (dir. Bradley Cooper), and Sproutland (dir. Cynthia Wade). A graduate of NYU Tisch School of the Arts, Trinity Laban (UK), and the Salzburg Experimental Academy of Dance, her choreographic work has been presented at Jacob’s Pillow, PS21 Chatham, La MaMa, WSA Studios, and Art Cake NY.

She has served as faculty at Jacob’s Pillow, Harvard, Yale, and Phillips Academy Andover, and brought her classes, workshops, and retreats to movement spaces across LA, Montreal, NYC, and the Hudson Valley. She is the creator of Tuesday Night Dance, the celebrated movement class hosted in collaboration with PS21 Chatham. Sayer is also the founder and creator of INNERSTANDING, a movement practice, language and online platform for embodied living and brighter being.

Lesley Mok is a New York City-based percussionist and sound artist. Their work is guided by a continual search for the connection between the mundane and the divine, the experience and manipulation of time, and a desire to capture emotional dissonance and complexity. Lesley is inspired by American experimental music as informed by the lineage of the AACM, sounds and textures from the natural environment, Afro-Cuban folkloric traditions, drumline, and songwriters and composers like Arthur Russell and Ryuichi Sakamoto.

Lesley’s ongoing explorations with composition and improvisation are most notably documented in their debut album The Living Collection (released May 2023 on American Dreams Records). The album, described as “an exquisite and stimulating work” by All About Jazz and “a singularly personal statement” by Jazz Trail Magazine, was named International Debut Album of the Year at the 2024 Deutscher Jazz Preis. Their solo LP transient will be released in July 2026 on American Dreams Records.

 

Brian Chase, a Brooklyn-based drummer and sound artist, plays for Grammy-nominated rock band Yeah Yeah Yeahs, NYC’s experimental music community and his solo project, Drums and Drones. As a versatile performer, music has taken him across the world to such notable stages as the Sydney Opera House, Royal Albert Hall and Hollywood Bowl as well as countless independent art spaces of music’s ‘underground’ communities. In 2018, Chase started Chaikin Records, an independent record label which spotlights pioneering figures of the avant-garde. The inaugural release on Chaikin Records was Drums and Drones: Decade, a triple album with 144 page book, described in The Wire as “an indispensable statement on how drummers hear sound.” Additional releases featuring Chase on Chaikin Records include albums with harpist Zeena Parkins, pianist Anthony Coleman, saxophonist Catherine Sikora and a collaboration with visual artist Keti Kartveli. As an educator Chase has taught at Bennington College and was a guest artist at So Percussion’s SoSI festival and Yarn/Wire’s summer institute. Chase’s writings have appeared in John Zorn’s Arcana series, culture blog Talkhouse and drumming trade magazine Modern Drummer. For more info visit chasebrian.com and chaikinrecords.com.

 

Booker Stardrum is a composer, drummer/percussionist, and producer. Stardrum has been involved with countless experimental and improvisational collaborations, pop projects, film scores, and sound design productions, and has released four solo records (’Close-up On The Outside’ in 2026, ‘Crater’ in 2021, ‘Temporary etc.’ in 2018, and ‘Dance And’ in 2015). Stardrum’s music is a highly personal amalgamation of electro-acoustics, minimalism, ambient, jazz, and contemporary experimental electronic music. His compositions are sculptural, carved from the dense layering of instruments and manipulated samples, a pantonal harmonic sense, and an intuitive approach to rhythm.

Stardrum’s collaborators include SML, Play Time, Lisel, Photay, Horse Lords, Wendy Eisenberg, Amirtha Kidambi, Jefre Cantu-Ledesma, Chris Williams, Patrick Shiroishi, Carl Stone, Lee Ranaldo, and Nels Cline. His discography includes solo and collaborative releases on independent labels such as International Anthem, We Jazz, Balmat, NNA Tapes, Northern Spy Records, Mexican Summer, Suddenly Quarterly, and Luminelle.

Booker lives in the Hudson Valley in New York State.
