For two and a half decades now, trumpeter Brian Lynch has been one the most reliable sidemen for pianist and salsa patriarch Eddie Palmieri, and he’ll be in tow when Palmieri plays the Mayne Stage on April 22. But before Lynch became so strongly identified with Palmieri, he earned acclaim as a member of Art Blakey’s Jazz Messengers, the ultimate university of hard bop; he’s also played for significant stretches in bands led by Phil Woods, Horace Silver, and Benny Golson. This is all a long way to say that, as much of a force as he is in the world of Latin jazz, Lynch is also a killer exponent of mainstream bop—and that’s the mode he’ll be in this weekend for a two-night stand at Andy’s.
