Will Toledo, the 23-year-old who records as Car Seat Headrest, isn't really a new artist. His last album, Teens Of Style, compiled songs from the 11 albums he'd already recorded and made available on Bandcamp. Teens Of Denial, which comes out May 20, contains new songs recorded with power and presence. The music puts a more polished edge on Toledo's self-deprecation, cynicism and honesty. Rarely does teen angst sound so fun.
