Haim came out of nowhere, improbable as Lana D.R. - in fact, not improbable at all - everyone in music is popping out all over, these days, springing up like hey presto. This song has a zany-infectious thrill to it, because it is such in-yer-face pure girl pop, channeling Fleetwood Mac and Wacko Jacko, and any number of MTV hits from 1982. 30 years later, this still seems like the best song Pat Benatar never had. Really a treat.
