L.A. sister trio HAIM -- the moniker comes from their last name -- first caught peoples' attention with their breakout performance at this year's SXSW and it seems that the buzz has only amplified since then.  With their debut EP, Forever, out and a slew of shows with Mumford & Sons this summer, it would appear that these siblings are poised to attract new fans by the minute, branching out beyond the music industry/blogger types that have been obsessed with them since their Austin show.  In their video for the EP's lead single "Forever," watch the girls ride around on motorcycles, get down in a hair salon and show off what we assume to be old family home movies -- their parents are musicians and the girls cite them as some of their biggest influences.
