Big night next Sunday (Nov. 16) at the Jazz Bakery: The Gathering, a multi-racial, multi-generational ensemble representing over 40 years of L.A. jazz history, will stage a two-set performance celebrating the release of its new CD The Roots and Branches of LA Jazz. Here’s a short list of players who will be signifyin’: Dwight Trible (vocals), Phil Ranelin (trombone), Michael Session (alto sax), Kamasi Washington (tenor sax), Miguel Atwood-Ferguson (viola), Roberto Miranda (bass), Nick Rosen (bass), Brandon Coleman (piano), Kharon Harrison (drums), and J.J. Kabasa (African drums). Led by reedman Jesse Sharps, this amazing line up will be featuring music from the CD as well as many new pieces, including some based on Eddie Harris’ Intervallistic Concept. (Go here for our archived Downbeast interview with Mr. Sharps.) This is a once-in-a-lifetime concert — and one hell of a way to celebrate the country we awoke to on November 5.
