We’ve seen what the Sigur Rós singer can do with nothing but an acoustic guitar inside a small LA record store, but now let’s watch him on national television with a headdress, backed by two drummers, electric guitar, piano, and keyboard. Spoiler alert: Jónsi and friends killed it. Enjoy their rendition of “Sticks and Stones,” off the How To Train Your Dragon soundtrack, above (via Audio Perv), but save it for the morning if you hope to hit the hay anytime soon. The thrilling percussion alone is worth the price of admission and a bout of inspired insomnia.
