The Houston Blues Society Blues Jam is one of our favorite events of the month, and this month it’s hosted by one of our favorite players, John Calderon. John has toured the world with the likes of Al Jarreau, Bobby Lyle and Regina Belle, but tonight he brings it all down to the little dive on Kirby Drive. The jam commences immediately after the host set. If you’re a musician. bring your instrument. If not. just bring your ears.
