Who knew? Bethany Cosentino from Best Coast doesn't only live on punk-pop and peaceful surf-rock. The California girl goes all soulful (or at least she tries to) during a special concert by rapper Kendrick Lamar. Together, they play “No Make-Up (Her Vice)”, from Lamar's “Section.80” (Top Dawg, 2011). The girl does alright, we think. Impressions?
