Jerome Richardson's "Groove Merchant" arranged by Rich Sigler is a gospel rock groove that fits perfectly. Played at 132 BPM, with straight eighths, this chart is packed with goodies like written-out solos for trombone and trumpet, lead trumpet range to written G on top of the staff, a few clever modulations, and a great development section. Toss in the optional parts to include vibes and you have a fine chart. Very effective at any performance. (3:37).
