What's the band/song at the beginning of the 2011 Packers/Eagles Wildcard football game?

It plays for about 20 seconds while showing slo-mo shots of players, after wards, it switches to the NFL intro song and Joe Buck starts talking. The lyrics during this portion are simply a very slow, "Oooooh, hooooo, ohhhhhhhh", four times in a row, with some nice rock guitar with it.....very good vibe!
