‘The Either/Orchestra 25th Anniversary’

The New York edition of this dependably marvelous Boston big band’s 25th anniversary celebration augments their formidable lineup with keyboardist John Medeski, trombonist Josh Roseman, bassist Mike Rivard, and Ethiopian singer-keyboardist Teshome Mitiku. The sophisticated and thoroughly entertaining ensemble’s deep book includes music inspired by an Ethiopian field trip, high-falutin’ fun such as “There’s a Bus That’s Leaving Soon For Alban Berg’s House,” Sun Ra-vian collective improvisations, and standards by Ellington, Monk, and Bobbie Gentry.
