The Shins appeared on Late Show With David Letterman last night, performing the lead single from their just-released Port of Morrow album.

Having listened to "Simple Song" a few times now, its chunky riff wouldn't sound out of place from a 1970s arena-rock band. Of course, since it's courtesy of the Shins, their sweet n’ sour approach to power pop keeps things from getting too overly grandiose. Listen to it above.

They also delivered an excellent hour-long set for the Live At Letterman webcast, which you can stream over at Paste

Are you digging the Shins' new material? Have you heard Port of Morrow in its entirety yet?
