Tommy Thayer, KISS's lead guitarist, and German metal singer Doro Pesch will appear at "50 Years Of Kiss In Germany: Official Fan Celebration", an event marking the band's anniversary. The gathering will take place at the Mitsubishi Electric Halle in Düsseldorf, though KISS themselves will not perform, with tribute act KISS Forever Band providing the live music instead.

Thayer will join KISS Forever Band's set as the event's featured special guest, with limited signing and photo opportunities also on offer, while Doro Pesch will join him for the musical finale. Additional special guests Ossy Hoppe and Didi Zill are also billed to appear, alongside exclusive merchandise, rare KISS memorabilia and limited music releases. The event takes place on 30 October 2026, with tickets going on sale on 11 August 2026 and fans able to register interest via kissonline.com, though registration does not guarantee admission.
