Adam Tendler is a “daring pianist” praised for his “adventurousness and muscular skill” (The New York Times). The Grammy-nominated artist has been called “the hottest pianist on the American contemporary classical scene” (Minneapolis Star Tribune), “relentlessly adventurous” (Washington Post), a “remarkable and insightful musician” (LA Times), an “intrepid… maverick pianist” (The New Yorker), and “one of contemporary classical music’s most intentional and daring pianists” (Seven Days).

A pioneer of DIY culture in classical music, at age 23 Tendler performed solo recitals in all fifty states as part of a grassroots tour called America 88×50, the subject of his memoir, 88×50. He has since become one of classical music’s most recognized and celebrated artists, receiving Lincoln Center’s Emerging Artist Award, the Yvar Mikhashoff Prize, and appearing as soloist with the London Symphony Orchestra, LA Phil, Sydney Symphony, Toronto Symphony Orchestra, NJ Symphony, Vermont Symphony Orchestra, as well as on the main-stages of Carnegie Hall, the Barbican Centre, Sydney Opera House, BAM, David Geffen Hall. Walt Disney Concert Hall, Milan Fashion Week, and other leading series and stages worldwide.

As a recording artist, he is featured on Wild Up’s Grammy-nominated third volume of Julius Eastman’s music, and has also released albums of music by Franz Liszt, Robert Palmer, and of his own original work. He recently commissioned and recorded 16 new pieces using the entire inheritance left to him by his father after his unexpected death, including works by Laurie Anderson, Nico Muhly, Dev Hynes and Missy Mazzoli, as part of a program called Inheritances. Soon to be featured on CBS Sunday Morning, and a New York Times Critic Pick, the Times said of the album, “You will be moved, profoundly and intensely,” and described the project as “a display of contemporary compositional force… a true show…emotionally involving…with a sense of true dramatic stakes.” Tendler’s 2024 immersive installation, Exit Strategy, as Green-wood Cemetery’s artist in residence, received national attention and engaged hundreds of contributing community members. He is the author of two books, a Yamaha Artist, and serves on the piano faculty at NYU.

Ariadne Greif, praised for her “luminous, expressive voice” (NYTimes), her “elastic and round high notes” (classiqueinfo), and her “mesmerizing stage presence” (East Anglian Daily Times), began her opera career as a ‘boy’ soprano in the Los Angeles area and at the LA Opera, eventually making an adult debut singing Lutoslawski’s Chantefleurs et Chantefables with the American Symphony Orchestra. She starred in roles ranging from Therese/Tirésias in Poulenc’s Les Mamelles de Tirésias, singing a “thoroughly commanding and effortless” run at the Aldeburgh Festival, a “sassy” Adina in The Elixir of Love with the Orlando Philharmonic, to Sappho in Atthis by Georg Friedrich Haas, for which the New York Times noted her “searing top notes,” and “dusky depths,” calling it “a solo high-wire act for Ms. Greif,” “a vehicle for Ms. Greif’s raw, no-holds-barred performance,” “one of the most searingly painful and revealing operatic performances in recent times.”

Sister Sylvester is a multimedia artist based in New York and Istanbul. Her most recent works, Constantinopoliad, won the Interactive award at CPH:DOX 2025, and Drinking Brecht, an interactive documentary, premiered at IDFA 2024. Both continue to tour internationally. In collaboration with Deniz Tortum she created the VR documentary Shadowtime, (’23) which premiered at the Venice International Film Festival and toured to festivals including IDFA, GIFF, Thessaloniki Film Festival and SXSW; and the film Our Ark which premiered at IDFA (’21) and has screened at festivals internationally. In her live work she creates visual essays and books that become performances, spatial narratives that play with spoken and written text to create communal reading experiences. Most recently Constantinopoliad (live), with a score by Nadah El Shazly, was commissioned by the Onassis Foundation, and premiered at National Sawdust in NYC (‘23) as a site specific work in the Onassis Library, Athens, and at the Internationaal Theater of Amsterdam; and The Eagle and The Tortoise showed as a work-in-progress at National Sawdust NYC, and premiered at IDFA On Stage (‘22), and in NYC as part of Under The Radar 2024. She is a Creative Capital fellow, a current resident at ONX Studio; a 2019 MacDowell Fellow; an alumnus of the Public Theater New Works program and CPH:DOX lab. She co-teaches a bio-art class at Colorado College, and has also taught and lectured at MIT, Princeton, UCCS, Columbia University, and Boğaziçi, Istanbul.

Her work has been called ‘genuinely subversive’ by Time Out NY; ‘imaginative and original’ by New York Times; ‘pulse-raising’ by Exeunt Magazine, ‘apocalyptic’ by artforum, and an ‘otherworldly, intimate, off-kilter, queer artistic orgasm’ by Life Magazine, Greece.
