Call it a mini Kiss reunion in Wynwood as Gene Simmons, flogging his $2,000 boxed set “The Vault,” did an in-store at Walt Grace Vintage, a cars and guitars gallery, with Ace Frehley, his former band mate.

Like a divorced couple sharing old stories of their high profile marriage, the duo kept an audience — which included Barry Gibb’s musician son Stephen Gibb — rapt during a freewheeling Q&A session that touched on their time together in Kiss.

The pair, sitting in front of a wall of guitars that collector Frehley coveted, also strummed acoustic guitars. This led Simmons to quip how difficult it was to play a vintage tune like Kiss’ “She” unplugged.
