Mac DeMarco’s debut full length, 2, released in 2012, cleaned up the songwriter’s warped take on soft rock and brought it to a broader audience. Given DeMarco’s affinity for keeping things lo-fi — 2 was the first time he’d bothered to record demos — it’s revealing to hear these songs in their most embryonic form. The performances here are a lit- tle looser and the sound a little hazier than on the actual LP, lending an atmosphere of dreamy vulnerability, especially to ballads like “Annie” and the Lennon-esque “Sherrill."
