Buffy Sainte-Marie at The Ark. A largely neglected major voice of the ’60s folk revival, this Canadian-born Cree Indian – featured at this past January’s Ann Arbor Folk Festival – is a spellbinding singer and gifted songwriter whose complex, enigmatic artistic personality expresses itself in a panoply of genres and guises, from protest anthems and Native rights songs to nature odes and love songs both tenderly elegiac and raunchy. Her current concert repertoire includes both favorites from her best-known ’60s recordings (like “The Universal Soldier”) and several new songs that are every bit as good. As a performer she blends a charming, childlike playfulness with biting, irreverent observations on society and politics. Don’t miss this rare solo performance. Thursday at 8 p.m. at The Ark, 316 S. Main in Ann Arbor. Tickets cost $50 at mutotix.com, theark.org, and 734-763-TKTS.
