It's gotta be in the genes! This month we welcomed HAIM into the VH1 You Oughta Know family of musical artists. The trio of rockin' real life sisters have been talking the world by storm with their debut album Days Gone By. Their parents must be so proud!

The bond between bandmates is always pretty strong, but that's doubly true when you're...you know, actually bonded by blood and all. Some of our favorite groups over the years have been sister acts that stole our hearts with their killer hooks...and killer looks. From blue grass babes the Dixie Chicks (well, two of 'em), to disco queens Sister Sledge (all of 'em), and rockers like the Bangles (two, too), these sisters sure know how to bring a house down. Head up to the gallery above to check out 15 of our favorite bands who made rock 'n' roll a family affair!
