Smile Now Cry Later just began playing shows, but has already become something of a local sensation. Until recently, one-woman band Lizeth Santos was the backup dancer for electronic dance wizard/husband Rafter, but decided to pursue her own music after a song of hers used in a MAC Cosmetics commercial left people clamoring for more.

Santos is continuing her fashion industry flirtation with the video for “Big Booty Butt.” Created for entry in the H&M Battle of the Bands contest — you can vote for her here — the video captures a typical, high-energy Smile Now Cry Later performance. It was shot by Jeannette Deron during the April 17th show at the Tin Can Ale House and edited by Rafter. The kinetic clip captures Santos hard at work, serving up drums, loops, and vocals for the eager crowd. It’s not easy to get San Diegans to shake their booty butts like that, and that bodes well for what is likely to be a prosperous career for Santos.
