If it hasn't been exactly a tidal wave, then there's at least been a ripple of a revival in early 90s US slacker rock in the UK over the last few years, with the likes of Mazes and Yuck. They're followed by the London trio Happyness, whose debut is a low-key joy. Weird Little Birthday is beautifully recorded, and everything sounds in the right place, delivering exactly what it needs to: it has a humid, enervated air, like a too-long afternoon in the park with too many bottles of wine. The half-whispered vocals are placed high enough in the mix that the quirks of the lyrics are evident – "I see people come in twos, just like breasts do" or "Remember when we broke into the park and you got laid and I watched and you said that was fine." All of which would be so much detail if the songs were nothing to shout about, but Happyness switch effortlessly between fuzzy pop and downcast, desolate ballads, alternately thrilling and charming.
