2007's 'Era Vulgaris' finds QOTSA touching on a variety of styles, incorporating electronic and acoustic textures alongside the band's trademark heavy rock crunch. The album includes such fan favourites as 'Sick, Sick, Sick', '3's & 7's' and 'Make It Wit Chu', with guest appearances by Julian Casablancas of The Strokes and frequent QOTSA collaborator Mark Lanegan.
