Going to an A Hori Buzz concert is a bit like buying a pig in a poke.

Aaron Tokona's psychedelic rock and soul collective has an ever-changing live line-up and anybody is welcome to join in the jam.

"It's different every time and it can be quite a train wreck," Tokona says, who used to be a member of Bongmaster and Weta before hooking up with singing drummer Nick Gaffaney to form highly acclaimed duo Cairo Knife Fight.

"But when it's on, it's on," he promises.

Whereas the line-up used to be loose, A Hori Buzz now has four core members. On his upcoming tour Tokona is being joined by Riki Gooch (Trinity Roots, Eru Dangerspiel), LA Mitchell and his cousin, Hori.

Jamming with A Hori Buzz is a completely different affair from working with his other outfit. "Cairo Knife Fight is heavily rehearsed. A Hori Buzz is just a whole lot of fun, like a musical holiday, and we just go on tour whenever we want," he explains.

The band has a standing open invitation to join them jamming, which sometimes ends in up in messy gigs, but Tokona says, he's much better these days at holding the show together.

"I just yell out a chord and it's still pretty loose, but I quite like it that way," he says. "We have four core members now, who know the songs and whatever comes on top is fine."

Now he's really looking forward to this weekend's gigs. "It'll be a good time, it's danceable and it's quite exciting as there's no real structure or formula," he says.

A Hori Buzz will be supported by Aio Aotearoa (Wellington), Flash Fullas (Adi Dick and Pet Johnson) and SoulSystem (from Christchurch).
