HAIM/TENNIS, THE DEPOT, Thursday, May 22, 8 p.m., $21

Haim is certainly one of the breakout music stories of the past year, as the debut album by sisters Este, Danielle and Alana Haim, Days Are Gone, has been a slow-burning success since arriving in September on a wave of huge buzz about the siblings pop-rock sound. They've been performing together for years even though they're all still way young--they had a family cover band with their parents before the three sisters started writing their own songs and struck out on their own. That was a good decision. Songs like the title track, "The Wire" and "Falling" helped draw rave reviews of the album from critics happy to hear some classic-sounding Cali rock, full of hooks and harmonies. The band has won over crowds at giant festivals and on club tours, as well as stints opening for the diverse likes of Vampire Weekend, Florence and the Machine and Mumford and Sons. Tennis opens the show.
