They'll be joined on stage by the band that arguably started it all, popular local band Gorilla Biscuit (three of the Opshop guys were members of Gorilla Biscuit in Christchurch in the early 1990s).

A dear life-long friend of Opshop, and former member of Gorilla Biscuit, recently suffered a serious health setback, so the boys are coming together to raise funds to help him get back on his feet.

This is the first Opshop show in Christchurch in 9 years, and it's the first time both bands have ever performed together.

This very special one-night-only event will sell out, so get your tickets now!
