Following their sold-out gig at the legendary Madison Square Garden Monday night (March 30), British art-rockers Alt-J have announced new dates for their extensive North American tour. You can get ticket information for the new dates here -- and check out the full itinerary below.

Taking advantage of their time in New York City, Alt-J also performed on The Tonight Show With Jimmy Fallon last night (March 31). Check out their rendition of “Every Other Freckle” below:

Alt-J’s sophomore effort, This Is All Yours, hit store shelves last year and received a Grammy nod for Best Alternative Music Album (losing to St. Vincent). Additionally, Diffuser was proud to award the disc the No. 1 spot on our list of the best albums of 2014.
