If we were to judge all up-and-coming bands by the calibre of their tour mates, Band of Skulls would arguably be top of the pile, having opened for Muse, The Dead Weather and The Black Keys in the past few years. Of course, sought after support-slots like these can’t be explained away by affable tour-bus behaviour and impeccable dressing room etiquette. No, it’s all down to the Southampton-formed trio’s impressive ability to raise a filthy blues-rock racket that totally belies their numbers. New album Sweet Sour showcases that in satisfyingly eardrum-rattling style, while also revealing their more mellow side on pared-back numbers like ‘Navigate’.
