Octobop, a northern California octet that carries on a West Coast tradition of hip jazz bands that get a swinging big band sound out of a mid-sized group. Leader/saxophonist Geoff Roach, guitarist Jack Conway, bassist Brian Brockhouse and trumpeter/flugelhornist Randy Smith provide the appealing arrangements for the group that also includes saxophonist Eric Patience, trombonist John Schermer, drummer Michael Henning and vibist Rick Gray.
