This week, Metallica are hosting a series of concerts to celebrate their 30th anniversary as a band.

At Monday night’s kick-off show at the Fillmore in San Francisco, they brought out a number of special guests, including former bassist Jason Newsted.

Frontman James Hetfield announced Newsted as “someone who lived with us, and toured with us and did stuff with us for 14 years.” Newsted then played 'Harvester of Sorrow' with the band, including his replacement Robert Trujillo.

Afterward, Hetfield begged Newsted to stay for another song, and he and the band played 'Damage Inc.'

Other guests at Monday night’s concert included host/comedian Jim Breuer, members of Diamond Head, John Marshall from Metal Church, Apocolyptica and Soul Rebels.
