Sigur Rós have announced their new headlining North American tour dates for early next year. Also, for every ticket you purchase, you will receive a new 3 song EP. To find all the dates and information, head over to the band's site.
I saw them awhile back and they put on a really good show. If they are playing in your state, I highly recommend seeing them live. You want be disappointed. Plus, I heard they are getting new visuals for this tour.
