As any seasoned Lollapalooza concertgoers knows, once a day at Grant Park comes to an end the late-night festivities are just getting started. And to ensure a rockin' good time from sun-up to sun-down, don't forget to RSVP to Spin and Dell Lounge's afterparty hitting South side venue Reggie's tonight, and featuring live sets from dark alt-rock duo the Gutter Twins and British electro-punks Does it Offend You, Yeah?

Admission to the party is free, but an RSVP is necessary; click here to ensure you're on the list for tonight's extravaganza!

But before the afterparty, while you peruse the Lollapalooza grounds at Grant Park, be sure to stop into the Dell Summer Rocks Dome, which offers fans a reprieve from the sweltering sun with activities aplenty. In the Dome, concertgoers can compile a digital mixtape, create a band button, design a custom T-shirt, score temporary tattoos, meet Dell's resident artist, Mike Ming, and catch sets from some of Lollapalooza's hottest performing acts, including Girl Talk, the Whigs, and the Go!
