Metallica spent the last week celebrating its 30th anniversary by releasing songs that have been unheard of before,  playing a few shows at the Fillmore in San Francisco, and having guest musicians sit in with them to jam.

On Friday, Cantrell performed live with Metallica on several songs, including “For Whom the bell Tolls,” “Nothing Else Matters,” “Seek and Destroy” and “Tuesday’s Gone.”

Dave Mustaine of Megadeth, former Metallica bass player Jason Newsted, and Danzig among others joined Metallica at the 30th anniversary shows at the Fillmore in San Francisco.
