Cleveland indie rocker Dylan Baldi of Cloud Nothings has been releasing records since 2009, when he was 18, spending what would have been his college years learning the ways of catchy, low-fi guitar punishment. Now he’s 22, and the third proper Cloud Nothings LP feels a little like graduation day. Baldi’s songs still bash and seethe, but with more flashy time-signature shifts, open space and studio trickiness. The torrid, seven-minute “Pattern Walks” is almost suitelike, and Baldi’s angst is cut with a wide-eyed ambivalence. A few years ago, a song called “Psychic Trauma” would’ve been radiant vomit. Here it’s almost majestic.
