Queens of the Stone Age singer Josh Homme contributes a guitar solo to this track. Biffy frontman Simon Neil was quick to praise the desert rocker's guitar skills to Kerrang!: "He came to the studio and listened to the song," he said, "and two minutes later, he was playing the best guitar solo you've ever heard." Drummer Ben Johnston added: "Josh didn't spunk all over the song. There's no fanfare saying, please welcome Josh Homme! He's everything you want in a rock star. He just added his take and it fits in with the song perfectly."
Geffen Records made history on June 27, 1994 when Aerosmith's "Head First" became the first major label song made available for exclusive digital download. Download speeds at the time were so slow it took around 75 minutes to download the track.
