The third annual RVAJazzfest is both fulfillment and valedictory for Dean Christesen. The first, featuring trumpeter and composer Steven Bernstein, started the national breakout for local band Fight the Big Bull. The second was a snow-impacted, all-local affair - trombonist Ray Anderson, himself a last-minute replacement for saxophonist Tim Berne - was grounded in NYC by a major blizzard. The third edition features not just a star player integrated into a local lineup but an entire band: Harris Eisenstadt's brilliantly engaging Canada Day. Also on the bill is veteran local drummer (Glows in the Dark, Ilad) Scott Clark's bracing and original 4-Tet (Clark, Jason Scott, Marcus Tenney and Cameron Ralston) and the debut of the all-star Old and New Things (Trey Pollard, Taylor Barnett, J.C. Kuhl, Adam Larrabee and Brian Jones), with instrumentation as varied as bass clarinet and banjo, and a playbook spanning the mathematical classicism of J.S. Bach and the ecstatic freedom of Albert Ayler. Catch RVAJazzfest at the Camel on Saturday, April 9, at 8 p.m. $15-$20.
