Jason Stein, a preeminent force in the world of Chicago Jazz music, and his band, Locksmith Isidore stop by the Hideout this weekend to play an album release show for their latest, “After Caroline,” which was digitally released on May 18th but the CD/LP doesn’t come out until June 15th. Stein’s infamous prowess comes from his choice of instrument, the incredible difficult Bass Clarinet. If that’s not enough to lure you in, Howard Reich, a reporter for the Tribune, and one of the most well-versed experts of the city’s jazz scene, listed it as one of the best things to do this weekend, in what’s shaping up to be a “jazzy” weekend across the city. Stop by, show starts at 9:00 PM.
