Alternative progressive metal band Tool gave their audience at their Halloween show at Monster Mash Music Fest in Tempe, Arizona by opening the show dressed as Led Zeppelin and performing Zeppelin's riffy masterpiece No Quarter.
Not too shabby of a job. Their likenesses of Led Zeppelin's members are pretty spot on too. You would barely know the difference if you saw them in person. As for the performance itself I'm pretty impressed. If anyone could pull off a decent cover of the song, it's definitely Tool. They also recorded a studio version of the cover that was originally released on the Salival box set that they put out.
Seems like it was a fun time for everyone involved. Always nice to see greats pay tribute to even bigger greats.
