There was talk of Johnny Depp in rehearsals with Stone Temple Pilots, so this shouldn't be entirely surprising. Depp showed up on Stone Temple Pilots tour opener last night with new lead singer Jeff Gutt in Santa Clarita, CA.
Depp played on "Sex Type Thing" and MC5's "Kick Out the Jams."
The band plays Ace of Spades March 13th.
