Metallica teamed up with The Roots and Jimmy Fallon for the unusual version of their iconic song.

Metallica have admitted they were felt “afraid” before playing their classic track ‘Enter Sandman’ on toy instruments during a recent TV appearance.

A few weeks ago, the band teamed up with Jimmy Fallon and his formidable house band The Roots for the unusual performance of one of their most iconic songs. Watch it below.

“We’re literally afraid to jam with certain people, because we think we’re not worthy enough. We’re not great musicians,” frontman James Hetfield told Spotify candidly.

“Even with those little flutes and stuff I was worried. Kirk [Hammett, guitarist] was practising the song on this little recording thing. It’s like, ‘Dude, stop practicing it – just go have fun. Go screw it up!’”

Hetfield added: “You’ve got to laugh at yourselves. You’ve got to not take yourself so seriously all the time. The Jimmy Fallon thing showed up in our lap, they said, ‘You want to do this?’ We had a blast. Stuff like that is just fun. It lightens your heart and it humbles you as well.”

Metallica released ‘Hardwired…The Self-Destruct’, their first album in eight years, on November 18. The band have since said they expect to be touring the record for the next two years. Before the album’s release, the band premiered their video for ‘Spit Out The Bone’ on NME.

Meanwhile, the band’s guitarist Kirk Hammett has called Guns N’ Roses a “nostalgia act”.
