Back in October, Pennywise fans got the news they had been longing to hear -- that frontman Jim Lindberg had decided to return to the band for their 25th anniversary show. Things appear to be going well, so Lindberg and the rest of Pennywise have decided to expand upon their touring plans with a full-fledged monthlong run in February and March.

The group will first play the Hollywood Palladium on Jan. 18 to celebrate their 25th anniversary with their longtime SoCal fans. After that, they'll take the next month to rehearse before launching their first extended run beginning Feb. 21 in Vancouver. The month-long trek will be primarily relegated to West Coast cities in the U.S. and Canada.

In announcing their reunion, guitarist Fletcher Dragge revealed that he decided to call Lindberg after "a little self introspection." After Lindberg announced his plans to leave the band, Dragge stopped taking his phone calls and Lindberg felt the longtime relationship was over.

In the interim, Lindberg went on to form and release a new album under the moniker the Black Pacific while Pennywise replaced the singer with Zoli Teglas. However, Teglas injured himself while on tour earlier this year and the recovery from his back surgery left the band out of action for much of 2012.
