METALLICA bassist Robert Trujillo and RATT guitarist Warren DeMartini joined ZAPPA PLAYS ZAPPA — the national touring project that finds guitar virtuoso Dweezil Zappa recreating the music of his late great father, Frank Zappa — on stage on Friday, December 11 at the Saban Theatre in Beverly Hills, California to perform a couple of Frank Zappa songs. DeMartini lent a hand on “I’m The Slime” while Trujillo came out for “Muffin Man”. Video footage of their appearances can be seen below (courtesy of California Rock News).

“The whole purpose of this is to have musicians who had no previous affiliation with Frank,” Dweezil told The San Diego Union-Tribune about his current band, “and to show that with — dedication and application — you can play this music the way it was meant to be played.”

Trujillo and his wife Chloe recorded a cover version of Frank Zappa‘s “The Torture Never Stops” for “The Frank Zappa AAAFNRAAAA Birthday Bundle 21. Dec 2010”, which is available on iTunes.

METALLICA is working on its long-awaited follow-up to 2008’s “Death Magnetic” album for a tentative 2016 release.

DeMartini is involved in a legal battle with RATT drummer Bobby Blotzer over Blotzer‘s decision to use and tour under the RATT trademark with an all-new lineup of musicians.

DeMartini filed a lawsuit in September against Blotzer, claiming that the drummer is falsely advertising his “tribute band” as the real thing.
