4-day tickets went on sale yesterday, however, single day passes have yet to be released.

We're also waiting on daily lineups to be announced from Lollapalooza. When they become available, we'll be sure to pass them on to you.

Lollapalooza 2019 is again at Grant Park in Chicago Thursday, August 1 through Sunday, August 4.

That being said, not everyone is super enthused about the lineup for this year's Lollapalooza.
