Can’t make it to the hinterlands of Tennessee?  The good folks from AT&T are showing off their ability to show stuttering video via their high speed networks with a live video webcast of many of the acts from this year’s alt music festival and arts extravaganza happening about 200 miles north of Atlanta. Two of my faves – Ben Folds is on the air at 3pm ET today and Elvis Costello will be up at 6:30pm Saturday – will be featured. Unfortunately, neither Death Cab for Cutie or Radiohead will be streamed from the AT&T site. Link to AT&T’s ‘BlueRoom’ live streaming is here.
