Listen to Arctic Monkeys on iHeartRadio

Arctic Monkeys got a little help from an old friend during a recent tour stop in Los Angeles. 

Queens of the Stone Age frontman Josh Homme joined the British rockers during the song "Knee Socks," which closed out the band's set at the Wiltern last week. 

Homme also plays on the studio version of the track taken from Arctic Monkeys new album AM.  He plays on the song "One for the Road" as well, and also produced the band's 2009 effort "Humbug." 

Arctic Monkeys frontman Alex Turner recently returned the favor by singing on the latest Queens of the Stone Age album, ...Like Clockwork
