Gallery 37 Center for the Arts, which commissions jazz artists to put together new projects for concert performance, has announced its fall schedule for the promising Downtown Sound Gallery series at the Storefront Theater. The series is a part of the Umbrella Music group, an impressive coalition of local musicians designed to guarantee that the local scene continues to thrive. It kicks off on October 2 with a panel discussion and demonstrations on personal approaches to improvisation. The music starts two weeks later with a double bill of groups presented by local reedist James Falzone and radical New York trumpeter Nate Wooley. Former Chicago reedist Matt Bauder, percussionist Quin Kirchner, New York alto saxophonist Rob Brown, and former Chicagoan Matana Roberts round out the series, which runs on alternate Mondays through December 18.
