The salad days, according to Mac DeMarco, are gone. "Rollin' through life to roll over and die," he sings on the title track of his immensely likable second album. Rarely has a reflection on ageing and obsolescence sounded so untroubled. DeMarco is a 23-year-old Canadian based in Brooklyn, whose easygoing approach to life – he likes to record at home in his underwear – gives his music a languid, carefree feel, even when the subject is chronic anxiety. The mood only really dips on Chamber of Reflection, when jangly guitars are replaced by a discombobulating synth and his downer sentiments are matched by the music.
