Deerhunter’s 2010 opus Halcyon Digest captures the dream-pop savants at their most elegant and fragile, but on their follow-up album, Monomania, Bradford Cox and company rediscover their scuzzy punk roots. “Neon Junkyard” rattles out of its cage with inhuman vocal contortions while “Pensacola” straddles over a hooky cowpunk guitar riff. The noisy title track cranks up the volume further and further, drowning out Cox’s screeching vocals with a torrential downpour of twisted feedback.
