Queens Of The Stone Age and Arctic Monkeys are, at this point, old buddies. Queens frontman Josh Homme produced the Monkeys’ album Humbug, Homme and Monkeys frontman Alex Turner traded guest appearances on their bands’ new albums, and Queens recently covered the Monkeys’ “Why’d You Only Call Me When You’re High?” during a BBC Live Lounge session. On Tuesday night, the Monkeys were playing for what sounds like a very excited crowd in both bands’ adapted hometown of Los Angeles, and Homme joined them onstage for “Knee Socks,” the new Monkeys song he sings on. Watch footage of the performance below.

The new Arctic Monkeys album AM is very good, and it’s out now on Domino.
