In addition to drums and traditional percussion instruments, So Percussion have made their own instruments and play everything from tea cups and walnut planks to flower pots and amplified cactus.

The group came together as graduate students at the Yale School of Music, though Jason Treuting is the sole remaining original member. Adam Sliwinski joined in 2002, Josh Quillen in 2006, and Eric Beach in 2007.

The group's initial purpose was to perform the repertoire of 20th century masters such as John Cage, Steve Reich, George Crumb, and Iannis Xenakis. After an encounter with David Lang, the Pulitzer Prize-winning composer and co-founder of New York’s Bang on a Can, their vision shifted and expanded. Their first commissioned work was his three-movement The So-Called Laws of Nature, in 2002. It was recorded along with Evan Ziporyn's Melody Competition on their self-titled debut in 2004 for Cantaloupe Music. Subsequently, they began commissioning new works from other composers including Steven Mackey and Paul Lansky, as well as Lang.

In 2005 So Percussion released an entirely different experience of Reich's classic composition Drumming. The four members played all nine percussion instruments, and the composer's own group of singers collaborated with them.

In order to extend their focus even further, they began to compose their own works, beginning with Amid the Noise by Treuting. It was released the same year with accompanying videos by Jenise Treuting. They went a step further in 2007, creating their own label shhh Productions, to release projects outside the parameters of their record deal with Cantaloupe Music. The debut release for shhh was an audio/video package of a performance of composer Dan Trueman's Five (And-a-Half) Gardens, recorded by So Percussion and Trollstilt with video art from Judy Trueman.

In 2008 they began developing the Music for Trains project in southern Vermont. The project took place during a month-long residency that centered around performances in and around Brattleboro and Bellows Falls, including their train stations. These performances included pre-recorded mp3 players -- to be listened to on the trains -- sundry materials gathered from the community, an on-stage sculpture by Ahren Ahrenholz, and video.

This was followed in 2009 by the evening-length production Imaginary City, inspired by Italo Calvino's novel Invisible Cities. The project used source material from the six cities that commissioned it and where it was performed: Brooklyn, Houston, Cleveland, Helena, Denver, and Burlington. It included video by Jenise Treuting and was directed by Rinde Eckert. That year also saw the creation of the So Percussion Summer Institute (SoSI), founded in 2009, on Princeton University's campus.

So Percussion's first recorded non-classical collaboration occurred on the 2010 album Treasure State with American electronic band Matmos. This was merely the opening gambit in an ongoing sonic expansion. Collaborations and appearances with artists as varied as Dan Deacon, Bobby Previte, Medeski, Martin & Wood, Glenn Kotche, the Dirty Projectors, and others followed. The ensemble were also appointed co-directors of a new percussion department at the Bard College Conservatory of Music.

Though it was written for them in 2005, So Percussion released their recording of Lansky's Threads in January of 2011. It was the beginning of a prolific year. In September, their reading of Reich's Malletts was issued as part of the composer's WTC 9/11 album on Nonesuch, and their own recording of Mackey's It Is Time was released by Cantaloupe. In October, Bad Mango, their recorded collaboration with Dave Douglas was released on the trumpeter's Greenleaf Music label, while they issued their own performance of Martin Bresnick's Caprichos Enfaticos on Cantaloupe. It was followed in November by David Lang's score/soundtrack for the film The Woodmans.

In March of 2012, So Percussion commemorated Cage's 100th birthday with a series of three American performances of his various works. Entitled We Are All Going in Different Directions, its spirit was in keeping with his aesthetic of indeterminacy; each evening's show was comprised of different pieces, and musical contributors Martin Schmidt, Deacon, Cenk Ergun, and Beth Meyers were enlisted. A unique, limited commemorative recording was packaged and sold in an edition of 300 copies. In September, the ensemble issued Where (We) Live in collaboration with guitarist, vocalist, and songwriter Grey McMurray. They also staged multi-artist, multimedia performances of the work. So Percussion's recording of Trueman's "laptop/percussion quartet with turntable" composition Neither Anvil nor Pulley (which first debuted in concert in 2010) was issued as a digital download in 2013.

Man Forever (John Colpitts, aka Kid Millions) enlisted So Percussion as co-billed collaborators for his spring 2014 release Ryonen. ~ Thom Jurek
