Valli Girls Haim

Haim's new album Days Are Gone debuted on Tuesday. It promptly shot straight to #6 on the U.S. charts and hit the #1 spot in the U.K. (no big deal, right?!). But hey, even though Este, Danielle, and Alana are totally ruling the music world now, you've gotta start somewhere.

And for two of the three Haim sisters, this meant performing in the Cali band Valli Girls. 

The all-female quintet not only sang songs like 2005's brilliantly-titled "It's a Hair Thing," but they also sported some wonderfully throwback fashion like colored hair extensions, a shaggy blonde 'do, and cargo pants with straps. The whole thing is seriously amazing, and it'll just make you love them that much more.

Not to mention, appreciate how far they've come from lines like "we never give up, never stopping, we conquer evil, then go shopping." Yeah...that happened.
