Metallica singer James Hetfield and bassist Robert Trujillo will perform with Alice in Chains guitarist Jerry Cantrell and drummer Sean Kinney at a benefit show in Los Angeles on May 12. The concert is a fundraiser for the MusiCares MAP Fund, which provides members of the music community access to addiction recovery treatment regardless of their financial situation.

Meanwhile, Metallica has been working on a new album and they will play some European festivals this summer.
