For the average rock-band follower, The Trons will almost certainly spark a second look.
For the rest of the world, there will be shaken or scratched heads, blank looks, and a great deal of "What the ... ?"
But the Trons will be taking centre-stage at Biddy Mulligans tonight as a very different part of the 2012 Hamilton Fringe Festival ... and there won't be a single human being among them.
The four-piece all-robot, fully-automated band has been considerably rebuilt by its creator, electronics engineering specialist Greg Locke, having been fitted out with new arms, new instruments and supercharged control system since he first constructed the band for the city's 2008 Fringe Festival.
The group is robotic band members playing two guitars, drums and a keyboard, and has literally been put together out of what 44-year-old Mr Locke says is salvaged electronics equipment.
"One 20-year-old computer runs it all," he says.
"It holds all the programme information which is fed to each player to play each instrument for each song. It took me between one and three days to programme each number, and it took a good bit of work and a lot of tweaking on timing to get it to sound okay."
Following the 2008 performance, Mr Locke took his robot band on tour overseas, with gigs in Paris, Berlin and more recently Malaysia. He says that at one stage, a video clip of the band "went viral on the internet" and attracted half a million hits.
Mr Locke says he's played in bands for 25 years, "but I'm not a great musician". Having earlier gained a degree in physics, he more recently studied at Wintec and gained a Media Arts honours degree.
"That degree had a research programme, so I was able to investigate and develop new ideas for the band. This resulted in doubling the playing abilities of the robots, and also writing a new album of songs."
He composes all his own music for the band.
"Now some of the band members can make up their own bits," he says.
"Sometimes it sounds a bit naff, but other times they come out with some great riffs. I'm never quite sure what to expect. I don't like to be any part of it once the band is set up - I just switch on the computer, then get a drink and stand among the audience.
"They sound just like a normal band - the main vocalist has a sort of garbled human voice, a bit like a lot of rock musicians who you can't really understand."
Mr Locke says that when he moves the band around New Zealand he "just throws it all in the back of the station wagon with the amps", but travelling overseas means he has to pull the robots and instruments apart and pack them all into boxes and suitcases.
In 2010 The Trons released a CD, which he says is the first rock album made entirely by robots. He is due to release a second album next year.
This year's Fringe Festival show is the first gig for The Trons since their revamp.
They will join three other more conventional music and performance acts, including The Redheads, Rumple and Stiltskin, and The Cult of the Dead Light-Bulb.
