Exclusive video: Jeff Pezzati of Naked Raygun joins Fall Out Boy onstage

At last night's Riot Fest in Chicago, pop-punk mainstays Fall Out Boy were joined for one song by punk legend Jeff Pezzati, whose band Naked Raygun helped define the sound of Chicago punk in the mid- and late-'80s. The band performed Naked Raygun's classic "New Dreams," from 1986's All Rise. Naked Raygun has a long history with Riot Fest, having re-formed for the fest back in 2006. We've got an exclusive professionally shot video of last night's performance—check it out below.
