As Z02, they. Re the hard-rocking Brooklyn band that's toured with Kiss. And as the Z Brothers, they pay the rent playing kids. Birthday parties. But as this new season begins, Paulie Z, David Z and Joey D have left music altogether. Even if their promiscuous manager and depraved club owner can get them back together, will the guys survive more ex-lovers, hot moms and strange gigs. As well as each other. On their way to rock & roll glory? Daryl Hall, Dave Navarro, John Popper, Bethenny Frankel, Dee Snider, Jim Norton, Chris Jericho, Frank Stallone, Jeffrey Ross, Warren Sapp, Constantine Maroulis, Marky Ramone and Joan Rivers co-star in this second season of the hit IFC series.
