Another day, another great band reveal for Festapalooza! Today, we're pleased to announce that Chicago rockers SOiL will play our inaugural concert on September 14.

SOiL is gearing up to release their new record "WHOLE" on August 20 -- not long before Festapalooza turns Festival Plaza into a madhouse. It also marks the band's first album since 2004 to feature singer Ryan McCombs and a return to form that has us chomping at the bit.

Digital Summer is also playing Festapalooza, and we'll be unveiling the entire lineup all this week first on the Free Beer & Hot Wings show each morning. Until then, keep the mystery alive by checking out a little hidden picture game we've put together that contains clues to the entire lineup.
