This is a video of musician Joe Porter covering several iconic rock and metal songs with percussion instruments, including “Metallica’s ‘Enter Sandman’ on the hammered dulcimer, Guns ‘n’ Roses’ ‘Sweet Child O’ Mine’ on the steel pan, AC/DC’s ‘Thunderstruck’ on the slapophone, Metallica’s ‘Master of Puppets’ on the flairdrum, the Red Hot Chili Peppers’ ‘Californication’ on the vibraphone, and Iron Maiden’s ‘The Trooper’ on the marimba.” Unfortunately, there was no Free Bird on the bongos. A shame, I know. But you know what they say: ♫ You can’t always get what you want, no, you can’t always get what you want, but if you try sometimes, you just might find…you get even less. ♫ Thank you for coming to my TED Talk.
