The whole “beach goth” trend might be all washed up thanks to what was, by all accounts, a disorganized and drenched mess of a Beach Goth festival in October. But the band that created the term and event of the same name are clearly surviving. Since the ill-fated fest, the OC rockers have been packing shows around the globe, including this third of three nights at the Wiltern. The band, led by comely crooner Brooks Nielsen, always defied classification, meshing melodious folk vibes with psychedelic surf punk and ska rhythms. When it comes to quirky style and subtly gloomy charisma, The Growlers always had the goods, but despite a lyrical disposition for death and dark shit, the “goth” descriptor was always a joke. Maybe “beach goth” has to die so The Growlers can finally prove that there’s more to them than a gimmicky genre name.
