Though a lineup for the event has not yet been announced, tickets for this summer's Lollapalooza [ tickets ] festival are now on sale.

Fans can currently purchase an "Early Bird 3-Day Pass" for $175 via the festival's website. Whenever the "Early Bird" ducats sell out, the price will then jump to $190, according to the site.

As previously reported, the Lollapalooza festival is set for Aug. 7-9 and will again take place at Chicago's Grant Park.

Organizers have not yet revealed which artists will be performing at the event. It is worth noting, however, that Jane's Addiction and Nine Inch Nails, who first shared a stage during the inaugural Lollapalooza tour back in 1991, will be mounting a co-headlining tour this summer.

Jane's frontman Perry Farrell co-founded Lollapalooza and continues to co-produce the event, which, a few years ago, was scaled back from a traveling festival to a one-off annual happening.
