This festival is only a few years old and the crowds are bigger every year. This lineup is quite huge. I mean there are just tons of artists on the list. 3 day passes tickets will sell out fast. Austin has a lot of hotels, but not that many. So if you plan to really come, I would book your hotel rooms ASAP.
I know there are a few other Ants living in Austin. I have been in this city for nearly a decade and I can answer any questions people have about the area. Anyone got a question about the city, send me a msg.
Also do realize many bands you see on the festival lineup, it is quite common for many of them to play side shows at other venues the same weekend. So you could easily see a band play twice the same weekend in this city.
October 2nd - 4th.
