NEW Lismore flashmob dance group The Cassettes are nearing the end of their first term together, with preparations well underway for their next show.

Assistant teacher Zoe Xanadu said she used to travel to Mullumbimby for lessons, but as a Lismore local she's thrilled a studio opened up nearby.

"I've always danced, I've always danced a little bit crazy, a little bit theatrical, but this is where I have full licence to be really crazy ... and have big hair," she said.

Dance instructor Marissa Treichel said she looked forward to the upcoming show at Star Court Theatre.

"It's such a beautiful theatre," she said.

"We're also doing a show at City Hall for Mental Health Week ... we're going to be performing at the Falls Festival, Mullum Music Festival, Woodford ... and we're actually looking for new dancers."

The Cassettes are an 80s Flashmob Dance group who come together to rehearse once a week for a main performance piece, as well as flash mobs.

"It's kind of like a pop up performance that lasts 10 minutes, and then we vanish, so it's just a piece of magic," Ms Treichel said.

Dance student Kylie Fuad joined last year in Byron Bay then swapped to the Lismore group.

"We just dance, we laugh, and we dress in fabulous clothes, and we bring joy to ourselves and to everyone who watches us dance, it's fantastic," she said.

The Cassettes dance classes now run in Mullumbimby, Byron Bay and Lismore.

Some of the hits they dance to include Don't Stop Believing, Push It, Living on a Prayer and Total Eclipse of the Heart.

New flashmobbers are required to graduate from the Absolute Beginners course.

The next course will be held for four weeks from October 12. Click here to join The Cassettes.
