That song is awful, Foster the People is awful, the only thing redeeming in that video is Craig Ferguson.
Actually, I watched that after posting that, I listened and I almost feel bad, because that was a great performance. I might actually care about them as a band if they sounded like that normally.
This is the best performance ever:
The Joy Formidable - Whirring (live at Glastonbury, 2011): http://www.youtube.com/watch?v=pKtF5FhJB1Q
An ending of EPIC proportions. And it all starts with a harp...
PS if you like that, check also their performance at KEXP 2011: http://www.youtube.com/watch?v=9kNQeDlgBoc
