Austin City Limits is a 3-day, 2-weekend music festival held every year in October. Nearly half a million people traverse Zilker Park in downtown Austin during these weekends to hear some of the biggest artists in the biz. This year, ACL brought in an impressive lineup, including Paul McCartney, Arctic Monkeys, Travis Scott, The National, Metallica, and Odesza. Austin is hailed as “the live music capital of the world” thanks largely in part to this festival. Here are some interesting tidbits from Austin City Limits 2018:
