Metallica drummer Lars Ulrich joined UK rockers Royal Blood for the final song of their set at Slim’s in San Francisco on Wednesday.
Ulrich teamed with the duo of vocalist/bassist Mike Kerr and drummer Ben Thatcher for the tune “Out Of The Black” from their 2014 self-titled debut album.
“Royal Blood” entered the UK album charts at No. 1 upon its release last summer on its way to becoming the fastest-selling British rock debut album in the UK in three years.
The group performed at Coachella last Saturday and will return to play at the festival again this weekend.
