Metallica have just released a four-track digital EP.

Called Beyond Magnetic, it features four songs recorded during the Death Magnetic sessions, but left off the album.

The band played one of these each night during last week’s four-night 30th anniversary run of shows at the Filmore in San Francisco.

The tracks are:

1. Hate Train
2. Just A Bullet Away
3. Hell And Back
4. Rebel Of Babylon
