It doesn’t happen often these days. The revered British string improviser’s visits to town are few and far between, so this stretch of dates, along with a mid-September hit at Roulette, are genuine events. His vocabulary for solo recitals is some of the most engaging guitar-speak around, and he’s trying out a handful of trios and duets as well. Of course, the high-vis pow wows with John Zorn and Laurie Anderson are the marquee gigs this week.
