Vevo announces the release of Best Coast’s live performances of “Everything Has Changed” and “Different Light.” With big guitars, direct lyrics, and a pleasantly laid-back attitude, the Los Angeles duo Best Coast play a tuneful version of punk rock that nods toward ’60s pop and ’90s alt rock informed by the sunny days of their hometown. The duo of guitarist/vocalist Bethany Cosentino and guitarist Bobb Bruno started off small, issuing a string of singles before becoming an internet-fueled sensation.
