The passage of time is important to Mac DeMarco. The pratfalls never stop, and the Viceroy scent of willful self-destruction may always follow him, but a surprising number of the 26-year-old’s songs are about that “same old boy” “getting older,” and even just reminiscing. The burnished acoustic pop of “This Old Dog,” the title track (and one of two new songs including “My Old Man”) from Mac’s upcoming LP, is in line with his continued worries about getting longer in the teeth. He evidently spent more time than usual on perfecting the songs for this album, demoing as he was preparing to make that West Coast move to Los Angeles all New Yorkers, native or not, think about. Don’t worry, parents and kids: Refining his craft doesn’t mean the goofball feeling has to change. That’s pretty close to the theme of “This Old Dog,” a shaggy ode to romantic constancy, come what may. The sentiment is a simple one, and while DeMarco is often aptly compared to Jonathan Richman, his crisply enunciated vocal here summons up vintage John Lennon. Y’know, Mac is 182 in dog years.
