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 4–6, and features the world premiere of SUPERDRUM X, a work featuring 100 self-playing drums by Dutch musical collective Touki Delphine featuring a different local 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 field day activities for the family leading up the performances: food trucks, free ice cream, apple picking, lawn games, and more. Join us.

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.
