Everyone in the Quin Kirchner Group is in other jazz bands as well, but don't think that the members won't be focused when they take the stage at Heaven Gallery, 1550 N. Milwaukee, tonight. The quartet, which originally formed as a one-off to fill a gig at the Hungry Brain, traffics in accessible improvisational music - and no, that's not an oxymoron.

The gig's at 10 p.m., with a $10 suggested donation. The Stein/Baker/Abrams Trio also performs.

Drummer Quin Kirchner promises you his full attention on Saturday night.
