Late-night TV hosts see hundreds of musical guests come through their studios, so it's always fun to see when one of them really gets stoked about a band he just saw. (I am not counting Jimmy Fallon in this. Jimmy Fallon is always stoked.) For a prime example of a stoked TV host, watch David Letterman reacting to TV On The Radio on last night's Late Show. But first, watch TVOTR blaze through a passionate, squalid, punk-as-fuck rendition of their soaring new single "Mercy," because it's the sort of performance worth getting stoked about. You can watch the performance and Dave's reaction below.
