Eric Schneider might be labeled a traditionalist–except that he’s got his ears open to newer sounds than those of the bebop masters who shaped his concept of the saxophone. But you can’t just call him a bebopper and be done with it either, because his comprehension of the swing saxophone giants is sure and prevalent. He’s that grand contradiction–a young veteran; he’s also a no-argument bitch-of-a-player. His two gigs this week find him with different bands, and I imagine that two distinct aspects of Schneider’s musical personality will emerge. On Saturday, Schneider the Young features the sparkling piano work of Mike Kocour as well as the vocalist JoBelle; both sail along the mainstream while evincing thoroughly modern sensibilities. On Wednesday, Schneider the Veteran shares the frontline with tenor man Eddie Johnson–whose sweet tone and hard drive make him the city’s preeminent swing saxophonist–and John Young, whose witty cutaways and lithe energy belie his years. Schneider himself could be considered, in many ways, a throwback, reveling in sheer virtuosity, fierce tempi, and the inner workings of classic tunes; but he avoids revivalism by turning these strong and recognizable influences into something that’s pretty much his own. Saturday, Moosehead Bar & Grill, 163 W. Harrison; 922-3640. Wednesday, 5 PM, Andy’s, 11 E. Hubbard; 642-6805.
