The Regrettes. Aren't they too young to have regrets? Lydia Night, the lead singer of this L.A. garage-punk feminist foursome is only 16. But what the Regrettes do have is songs, attitude, a major label deal with Warner Bros., and a buzz coming out of SXSW. With Active Bird Community and So Totally. All-ages. 4 p.m. Sunday at Kung Fu Necktie.
