Founded in 1985 by saxophonist & composer Russ Gershon, the ten-piece Either/Orchestra, based in Somerville MA, is one of the jazz world's most long-lived and distinguished groups.  Alumni include jazz stars such as John Medeski, Matt Wilson, Miguel Zenon, Jaleel Shaw & Josh Roseman.

The E/O, featuring a six piece horn section, piano, bass, drums and congas, has put its stamp on just about every style of jazz, from big band, swing and bop to Latin jazz, electric and avant-garde.  The last decade or more has found the band absorbing an Afro-Caribbean influence through a succession of Latino members.
