Metallica have been making the rounds in L.A. this past week, performing on Jimmy Kimmel Live! and playing an intimate show last night at the Henry Fonda Theater. And we’re not exactly sure how this all went down, but a TMZ tipster caught the band at a grocery store along with Billy on the Street’s Billy Eichner. Somehow, “Enter Sandman” was being blasted at the Gelson’s supermarket in Hollywood, and the butcher, along with the band, was rocking out hard. Sure, it was being filmed by Eichner and a camera crew, so we’ll probably find out what the whole thing is for, but it’s fun to see the guys hanging out and a butcher rocking out.
