Metallica paying tribute to Van Halen at a recent concert in Pasadena, California, hometown of the 70's rockers.

FOX's Laura Ingle takes you inside the music with this "Bonus Track":

Any rocker knows that bass riff as the opening of Van Halen's 1978 classic 'Running With the Devil,' but this is Metallica doing the honors at their July 29 show at the Rose Bowl in Pasadena, paying a little homage to the classic rockers while they were in the bands hometown.

Many know Van Halen was formed in Pasadena, California in 1972 by brothers Eddie and Alex Van Halen. Front-man James Hetfield lead his band through an abbreviated version of the classic, complete with an attempt to replicate David Lee Roth's iconic screams...

Metallica sharing professional footage from the concert on the band's Instagram page, at one point telling the crowd, "that's all I can sing," adding, "that was kind of fun."
