If they didn't already have you sold with Rise Against, Elvis and Iggy, organizers behind Riot Fest 2012 unveiled their second wave of headliners this week, a list that further extends the festival beyond its old punk roots.

Added to the lineup are Dead Sara, Minus The Bear, Andrew W.K., Hot Water Music, Neon Trees and more, according to an announcement posted on the Riot Fest website. The festival also released their day-by-day lineups so eager music fans can start planning their weekends for the mid-September event.

Compared to the city's other big-name summer festivals, Riot Fest passes are a bargain. $90 three-day passes, which include entry to two days of festivities on the Humboldt Park grounds plus admission to the Congress Theater on Sept. 14, are all sold out, but two-day passes are still available for $49.99, and single day passes are up for sale for $39.98 Friday and $34.50 Saturday and Sunday.
