Lollapalooza on Tuesday unveiled not only their daily set-by-set schedules and Chow Town food vendor lineup, the same day Chicago music fans who missed out on tickets to now sold-out festival were offered new hope to catch their favorite acts.

The Aug. 3-5 festival's schedule sets up some intriguing artist showdowns that will leave numbers of festival-goers in a quandary: Jack White or Justice? At the Drive-In or Florence + The Machine? Santigold or Frank Ocean?

And then there's the black-on-black showdown that will close day one of the festival: A (mostly) reunited Black Sabbath or Black Keys? Ticket-holders now have just short of two months to plot out their strategy to catch their favorite acts across the sprawling Grant Park grounds.

Tuesday also saw two other significant Lollapalooza announcements. Eater Chicago has the lowdown on the dozens of eateries Graham Elliot has recruited for this year's Chow Town lineup -- a combination of festival favorites -- like Kuma's Corner, Goose Island Brewpub and, of course, Grahamwich -- and newcomers such as MBurger, Chizakaya and Mercat a la Planxa.

Finally, 30 after-party concerts spanning no less than 13 venues citywide were announced Tuesday, the Chicago Tribune notes. Notable shows include Passion Pit at House of Blues on Thursday, Aug. 2, Tune-Yards at House of Blues on Friday, Aug. 3, plus Afghan Whigs at the Metro, Walkmen at Lincoln Hall and Chairlift at Empty Bottle on Saturday, Aug. 4.

Tickets to the aftershows go on sale 10 a.m. Friday at Do312.com.
