Don’t expect “Jesus, Etc” or “Handshake Drugs” during the Wilco guitarist’s residency this week – he has two or three other lives he wants to show you. Each involves some of the most intrepid improv maneuvers around, from pin-drop subtleties to balls-out skronk. BBC lets him rampage with fellow travelers Tim Berne and Jim Black. There will also be duos with other string players; the sets with Elliott Sharp and Mary Halvorson offer plenty of promise. But the kickoff show by the Nels Cline Singers is the must-see event. Long story short, their new Macroscope is a masterpiece of free-flowing interplay.
