If you haven't heard 'Brill Bruisers' yet, the brand new album from The New Pornographers, you can get an idea of what you're missing in the video above.

Celebrating the release of their sixth studio album (which was just released on Aug. 26) -- nearly four years after their last LP -- the eight-piece Canadian indie rock outfit made an appearance on 'The Late Show With David Letterman' last night (Sept. 3) to chat about the album and perform its swaying title track.

The performance was nearly flawless and just as peppy as the studio track. Compare their 'Late Show' performance with the studio track below:

The infectiously catchy album is now available via Matador Records. Get details on the release at the band's official website here.
