Them Crooked Vultures (formed in 2009) are a hard rock supergroup comprised of Dave Grohl, Josh Homme and John Paul Jones of Led Zeppelin-fame. The side project had been in the works since at least 2005, when Dave Grohl mentioned in an interview:

The next project that I’m trying to initiate involves me on drums, Josh Homme on guitar, and John Paul Jones playing bass.

Their self-titled debut was released in November 2009, with the song “New Fang” as the lead single. The band has been on hiatus since finishing their first tour in 2010.
