Sculpting spacey soundscapes over booming hip-hop beats, this SoCal band takes musical cues from up and down the West Coast. On 2013 debut I Love You., they blend G-funk grooves with slinky Maroon 5 pop. Lead vocalist Jesse Rutherford even morphs his vocals from crackling groans that echo the Deftones to reggae-touched raps that flow like Sublime. Their sound expands even further over the rest of their catalogue: slinky R&B (à la The Weeknd) filtering through murky layers of guitars that sound like synths dunked under the sea—an effect that's both dreamy and hypnotizing.
