Having recently celebrated their fifth anniversary, Beast have nothing left to prove – they’ve had critical and chart success, and enjoyed accolades with their individual projects. But did they still have that inner fire? The answer was a resounding yes – “Good Luck” is a killer song. It’s wonderfully cohesive, with speaker-quivering bass, a swath of strings, siren squibs and the higher registers of Yoseob and Hyunseung giving way to an elegant and sublimely catchy chorus. A simple yet effective dance-focused video was all the track needed (with a Last Supper scene thrown in for good measure) to demonstrate that the six-piece are nothing short of a world-class act.
