Here’s something delightfully unexpected.

Heavy metal legends Metallica appeared on The Tonight Show starring Jimmy Fallon to promote their upcoming album Hardwired… to Self-Destruct. The band paired up with Fallon and The Roots to create a completely different rendition of their classic Enter Sandman. Instead of pulsing guitars and heavy bass, Metallica opted for classroom instruments like the kazoo and xylophone.

It’s exactly the performance I wouldn’t expect from the group. It’s so different, I’m not sure it entirely works, but once again, kudos to Fallon & The Roots for arranging a classic song with classroom instruments and making it completely unique.

Funny enough, Metallica will make their entire catalog, including Enter Sandman, available on Napster on Friday. Metallica was responsible for killing Napster after suing the music downloading service for copyright infringement. But, the latest iteration of the streaming service is owned by Best Buy and was previously known as Rhapsody.

Regardless, good on Metallica for playing ball here. It’s always fun to see bands completely change up a hit song.
