Since 1991, musical worlds have collided for a good cause at the annual Tibet House Benefit. This year’s edition again mixes former “Downtown” stalwarts — including curator Philip Glass, Laurie Anderson, Patti Smith’s group, and Debbie Harry — with visitors from the hinterlands. The chakra-rocking Flaming Lips bring their Oklahoma oddness to town on the heels of their Beatles tribute, With a Little Help From My Fwends, while psychedelically inspired Kentucky country outlaw Sturgill Simpson will provide sturm-und-twang. But the wildest card could well be dazzling Cape Breton fiddler Ashley MacIsaac, who’ll be joined by his equally remarkable neighbor, Celtic keyboardist Maybelle Chisholm McQueen. Expect Philip’s cousin Ira Glass to perform some meta-radio magic, and submit to the Drepung Gomang Monastery monks’ ritual invocation.
