Harriet Tubman Double Trio

Normally a power trio of guitarist Brandon Ross, bassist Melvin Gibbs and drummer JT Lewis, Harriet Tubman doubles in size with the addition of cornetist Graham Haynes and two turntablists, DJ Logic and Val-Inc, to perform music from its most recent album, Ascension, which uses the Coltrane album of the same name as a spiritual springboard for slow-burning improvisation.
