A veteran of Chicago’s vibrant new and improvised music scene, bassist Josh Abrams is perhaps best known for making classical minimalism hip for indie rock kids, as a member of so-called “post-rock” mainstay Town and Country. His other collaborations are equally intriguing, beginning with an early incarnation of pioneering alt.hiphop group the Roots. After settling in the Windy City, he played with a veritable “Who’s Who” of Chicago improvisers, as well as recording and performing with the likes of Sam Prekop, Godspeed You Black Emperor!, Prefuse 73, Savath & Savalas, and Sticks and Stones. Also prolific as a solo artist and bandleader, his own work (sometimes as his alter-ego Reminder) varies from textured investigations of world music and improv to experimentation with bedroom beats and samples. Abrams visits Buffalo this week en route to Williamsport, Pennsylvania, where his bass playing will be part of the American debut of experimental composer Rhys Chatham’s new composition for 100 guitarists, Les 100 Guitares: G100. Joining Abrams for an intriguing set utilizing indigenous African instruments, multiple tape loops, and guitar is G100 “section leader” David Daniell. Known for swelling blues-drones and computer-generated layers of ambient electronic sound, Daniell will open the show with a solo set. —greg gannon
