There’s a real pleasure in hearing genetically linked voices singing together, as the individual ticks and characteristics meld in a single, dizzying tone, and especially these two with their burred Americana grace. Add to that the multifarious contributions of MJ Lenderman, playing drums, bass, electric guitar and 12-string, and Megafaun’s Brad Cook (bass, drums, recording and engineering), and you get an extraordinary debut record, wry and self-lacerating in parts and kick-down-the-amps rowdy in others.
