A fisherman’s waistcoat. Or a worn cap. Or a dodgy t-shirt. And of course, that disarming gap between his front teeth. Mac DeMarco is natural and cuddly. The Canadian singer-songwriter cites John Lennon and Neil Young as his major influences. However, the shining example is Jonathan Richman, the impish composer of classics like ‘Roadrunner’ and ‘Egyptian Reggae’. DeMarco’s tale is one of endless touring and temporary jobs. Until his second album ‘Salad Days’ (2014) met with some success. The mix of lounge jazz, sluggish slacker pop and ‘70s yacht rock was a good fit among contemporaries such as King Krule, Kevin Morby and Kurt Vile. Be prepared for anything. A DeMarco concert can turn into an impromptu sing-along that takes in the entire history of rock. Top entertainment.
