Jason Stein is a ubiquitous presence on the world class Chicago improvised music scene and beyond. He's a staunch force with a monogamous passion for his instrument of choice, the darkly sonorous and notoriously difficult bass clarinet. But Stein thrives as a leader also, as witnessed by his critically-acclaimed recent quartet release. However, no other aggregation he works with has quite the road legs, perspective, and intimacy of Locksmith Isidore, his long running trio with bassist Jason Roebke and drummer Mike Pride. Of late, this decade old unit has toured arenas throughout the US opening for comedy star Amy Schumer, who happens to be Stein's kid sister. Presenting avant jazz in such massive venues as Madison Square Garden and LA's Forum has cemented Locksmith Isidore's very special bond, which is more than apparent on their fourth album After Caroline."As Many Chances As You NeedEckhart ParkIda Like26-2SternumWalden's ThingYou Taught Me How To LoveWe Gone
