Either/Orchestra

The Either/Orchestra (E/O) is a jazz group formed by Russ Gershon in Cambridge, Massachusetts, US, in 1985. E/O is configured as a "small big band", with three saxes, two trumpets and one or two trombones. E/O's is characterized by a heavier and more orchestrated sound than that of a smaller jazz combo, but remains more streamlined and improvisation-oriented than most big bands. Provided by Wikipedia
