Before heading into the studio in early 2004 to record the fourth Queens of the Stone Age album, Lullabies to Paralyze, the band's guitarist/vocalist/chief songwriter, Josh Homme, kicked out bassist Nick Oliveri for undisclosed reasons. While Lullabies is hardly a concept album, its songs play off each other as if it were a song cycle, progressing from the somber Mark Lanegan-sung opening salvo of "This Lullaby" and steadily growing spookier with each track, culminating in the scary centerpiece "Someone's in the Wolf." The key to QOTSA's darkness is that it's delivered seductively and that seductiveness is all musical. Specific lyrics don't matter as much as how Homme's voice blends into the band as all the instruments bleed together as one, creating an elastic, hypnotic force that finds endless, fascinating variations on a seemingly simple sound. Simply put, there is no other rock band in 2005 that is as pleasurable to hear play as QOTSA - others may rock harder or take more risks, but no one has the command and authority of Queens at their peak, which they certainly are here.
