So Percussion Biography (Wikipedia)
So Percussion (styled Sō Percussion) is an American percussion quartet based in New York City.
Composed of Josh Quillen, Adam Sliwinski, Jason Treuting, and Eric Cha-Beach, the group is well known for recording and touring internationally and for its work with composers such as Steve Reich, David Lang, Caroline Shaw, Bryce Dessner, Julia Wolfe, Vijay Iyer, Fred Frith, Dan Trueman, Tristan Perich, Paul Lansky, Steven Mackey, Shara Nova, Martin Bresnick, Oscar Bettison, Evan Ziporyn, and Arvo Pärt. Originally formed when the members were students of Robert van Sice at the Yale School of Music, the group also continues to play works from the standard repertoire of percussion ensemble music—including works by composers such as John Cage, George Crumb, and Iannis Xenakis. In addition to their work with composers, the members of So Percussion produce original music, including large scale evening-length works.
The group is also well known for its use of unusual and exotic instruments in performance and on recordings, including glockenspiel, bowed marimba, aluminum pipes and an amplified cactus.
