Sat. Feb. 17

Chandler Travis - that jack of all genres and Cape Cod wise-acre - has a penchant for charitable works of music. He shepherds "Shaun & Suzi's 14th Annual Mardi Gras Ball" at T.T. the Bear's Saturday Feb. 17. You'll get not just Travis but assorted pals like Willie Loco Alexander, Andrea Gillis, Dennis Brennan, Sal Clemente (from Ultrasonic Orchestra), Bo Barringer (from the Collisions), the Steamy Bohemians and Bourbon Princess. How will they fit all those people into an 8:30 p.m. - 1 a.m. time slot? Don't worry, they'll do it. It'll cost you $12, and you'll feel better knowing the proceeds go to the New Orleans Musicians Clinic.
