Radical Something + Yonas + Sam Lachow

Radical Something registers as the apotheosis of frat pop, blending hip-hop, lite reggae and Dave Matthewsy sensitive-guy crooning into a smooth, sunny whole. This Cali trio will either delight or horrify you, depending on your personal chill quotient; as for us, let's just say we're hardly immune to the breezy charms of favorites like "Long Hair Don't Care" and "We Were Just Kids." Here, the boys turn up as part of their—deep breath…—Summer of Rad tour.
