Dananananaykroyd, Glasgow’s six headed, duel drumming, rock monsters – have every right to be extremely happy. They’ve just finished their debut album in New York, have been lapping up the acclaim for recent single Pink Sabbath, and are levelling bars and venues all across the country, on a massive headline tour. And their beaming exuberance is well earned: Monday’s set at the Harley was brilliant. Right from the start, the influence of their musical forebears in Fugazi and Blood Brothers is obvious. Taut, trebly guitars, duelling high-pitched vocals and chewed up song structures were all present and correct, but alone that’s nothing special. Across the UK, hundreds of bands with asymmetric haircuts and the first Bear vs Shark album are cooking up similar tunes, all destined to be forgotten as quickly as they were made. No, what makes Dananananaykroyd so irresistible is the secret ingredient so often forgotten by skinny kids with guitars: an unwavering sense of manic and wild-eyed fun. Within five seconds of the band skipping on stage, the temperature and excitement levels had rocketed. Brows were mopped, fringes wilted and jackets fell to the floor as the grinning Glaswegians spilled out into the packed crowd. Minutes later, The Greater Than Symbol and The Hash had destroyed any hopes of hearing anything else for the rest of the night, a new song had been previewed and the band’s job was already half done. A clutch of bonkers-pop classics, a group hug and some irrepressibly enthusiastic stage banter later, the band were gone, off to find hydration salts and somewhere cool and dark to lie down and recover.
