FIELDWORK is a collective of three widely celebrated young composer-performers:pianist Vijay Iyer, saxophonist Steve Lehman (formerly Aaron Stewart), and drummer Tyshawn Sorey (formerly Elliot Humberto Kavee). Fieldwork’s music reflects each member’s ties to the American jazz tradition, modern composition, African and South Asian musics, underground hip-hop and electronica, and the influential music of Chicago’s A.A.C.M.. Fieldwork’s intensely collaborative rehearsal process resembles that of a rock band: they use group improvisation to develop and expand their intricate compositions into something larger than the sum of its parts. The result is a dense yet visceral musical world — tightly unified ensemble playing, extroverted and high-impact, but with a mysterious inner logic.
