The thrash icons issue their Bataclan tribute Liberte, Egalite, Fraternite, Metallica! on Record Store Day (April 16) via Blackened Recordings. It's a live recording of the group's 2003 show at the venue, and Hetfield says there is an almost endless supply of unique live and studio recordings in the Metallica vaults.

In an exclusive interview for members of Metallica's website, Hetfield says: "There's such a freedom, having your own record company and being able to do cool stuff like this. And we've got so much stuff recorded, pretty much every show we've ever done since we knew you could record has been recorded.
