Outside Love, the last album from Black Mountain frontman Stephen McBean’s Pink Mountaintops side project, was one of 2009’s best and most underrated rock albums, an endlessly warm and welcoming set of stoned, fuzzy campfire singalongs. Since that one dropped, McBean has relocated to Los Angeles, and that move might explain why the new Pink Mountaintops album Get Back is so different. The new one is heedless, flopsweat-drenched, cocaine-hangover California party-rock, with some truly appalling rap verses in there. It’s a weird album. We’ve heard the early tracks “North Hollywood Microwaves,” “Ambulance City,” and “The Second Summer Of Love,” and now the whole thing is streaming at Pitchfork.

Get Back is out 4/29 on Jagjaguwar.
