Guitarist Mel Henderson slips easily into Wes Montgomery-style solos, organ wizard Gerry Youngman captures the allure of Hammond B3 that audiences never tire of, and drummer Sean Jefferson holds it all together on drums. The sum of the parts is Paradigm Shift, a trio that has enlivened Rochester clubs and festivals for two decades.

Paradigm Shift plays on Friday, August 21, at Bernunzio Uptown Music, 122 East Avenue. 8 p.m. $5-$8. 473-6140; bernunzio.com.
