For more than 30 years, 'Austin City Limits' has entertained TV viewers with live performances from their favorite musicians. Nearly a decade ago, the PBS series branched out beyond the constraints of viewers' living rooms to Austin's Zilker Park. The annual ACL Music Festival has established itself as one of the largest festivals in the US, attracting more than 65,000 people daily. This year, 130-plus bands will take the stages, including performances from the Eagles, Phish and the Strokes.
