Sigur Rós just uploaded a brand new song “Brennisteinn” to Youtube and we’ve already taken it for a spin multiple times. The song will be featured on their upcoming album Kveikur, due June 17/18 which you can pre-order now from their official site. The double vinyl for $25 is a steal. Sigur Rós play Late Night w/ Jimmy Fallon tonight and kick off a North American tour at Madison Square Garden this Sunday (March 24th). Watch the stellar video directed by Andrew Huang after the jump.
