Metallica frontman James Hetfield will be making his first public appearance since entering rehab last year.

Hetfield won’t be returning to the stage just yet, but he’ll attend the opening of a new exhibit showing off his hot rod collection at the Peterson Automotive Museum in L.A. Metallica was forced to cancel an Australian tour last fall when Hetfield entered rehab for his addiction issues.

The band will return to the road in April for a tour of South America.
