"It's been over 15 years since childhood friends Joshua Homme and Jesse "the Devil" Hughes founded their cartoonish, carnal blues-rock project, Eagles of Death Metal. When Homme's not manning the drum kit or the mixing board for Eagles (he's produced each one of their LPs) he fronts Queens of the Stone Age, one of the biggest hard rock bands on the planet. So it makes sense that listeners would categorize the group as a Queens of the Stone Age side project. But EoDM has never been Homme's show-this band has always been about Hughes, the strutting, showboating, irredeemably decadent presence at its center, the greasy cog around which the freak show turns ... Zipper Down mostly sticks to the formula of the duo's past three albums, frequently recycling structural and instrumental elements from past songs".
