True rock stars aren't of earthly origins—they descend from fugue clouds to gravitate on lyrical energy fields and spread pulsating messages about peace, love, and Flemish painters. See two supernovas of song bring the rock with today's Groupon: for $30, you get one 300-level ticket to Bon Jovi and Kid Rock at Soldier Field (a $66.50 value). The concert is on Saturday, July 31, at 7 p.m. Tickets in the 300 level are at the third level above the field.

With more than 120 million records sold, more than 2,600 concerts performed, and a million faces seen and rocked, Bon Jovi has carved out a New Jersey–sized place in the rock pantheon. The band's current trek into the stadiums and arenas of the world, The Circle Tour, ups the ante on live music with an 800,000-watt sound system and a 4,300-square-foot, high-definition video screen. Bona fide Bon Jovi fans can expect to hear songs from the band's most recent album, The Circle, as well as classic smash hits like "Livin' on a Prayer," "You Give Love a Bad Name," and "It's My Life." Opening act Kid Rock is no slouch himself—the Motor City music maker has blended rock, rap, and country into a sonic smorgasbord that has earned multiple Grammy nominations and sold millions of records worldwide. Concertgoers may hear hits like "All Summer Long," "Cowboy," and "Bawitdaba," which is "Kid Rock" spelled backwards.

Stir Soldier Field awake from its summer slumber and enjoy a night of rocking riffing and sentimental sing-alongs with your ticket to Bon Jovi and Kid Rock. Buy up to four Groupons and exchange them for tickets at Soldier Field's will call.
