With rumours of up to seven record deals on the table, and support slots for the Darkness and The Streets in the bag, tonight the mighty Goldie Lookin' Chain continue their unstoppable rise to infamy with a homecoming show at Newport's sizeable City Live Arena.

First up, though, is Culprit One, local cut-n-paste laptop guru. What James Hannam lacks in showmanship he makes up for with hypnotic beats and breaks. Standing onstage like a one-man Kraftwerk, he gets the crowd dancing early, while debuting cuts from his forthcoming Aqoon Guud EP.

Second support act My Red Cell seemingly swooped from nowhere (aka Barry) to the pages of the weekly music press at the start of the year, via a record deal with V2. From there they had a lot of expectation to justify, and playing second fiddle to a Newport comedy rap group wearing Matalan tracksuits surely wasn't in the grand plan.

It's hard to find their slightly derivative rock dislikeable. Singer Russell Toomey yelps and wails like the Welsh Jack White, and their spiky glam songs are never short of decent.

And yet, equally it's hard to find anything loveable about My Red Cell. We've been here before, with Terris at the turn of the century. Hubris isn't ever endearing, and My Red Cell are showing the worrying hallmarks of a band believing their own hype.

The last time we saw the Goldie Lookin' Chain here, they were supporting Super Furry Animals in October. To be headlining in such a short space of time shows how far their stock has risen in recent months.

And tonight they go down a storm. Pants are thrown on the stage, images from Tony Hart's GLC gallery are projected onto the backdrop, and a couple of mates sit on a sofa at the back skinning up and drinking stella.

Since Goldie Lookin' Chain essentially started by poking fun at the naffness of Newport wiggas, it's amusing that so many of their followers have embraced the lifestyle so completely. Do they not realise the group are laughing at them? Or do Newport residents have an extra heightened sense of irony?

It scarcely matters, because tonight everyone is having a killer time. With an audience made up of everyone from kids to elderly relatives, it's a wonder how such less-than-wholesome odes as Shit To Me and Your Mother's Got A Penis are so well received.

GLC could do with a bit of onstage repartee, and if anything their set goes on a bit too long, but everyone in the arena is on their feet and loving it. But since the joke really only works if the audience is already in on it, it's about time the Goldie Lookin' Chain got some records into the shops and let the rest of the country in on the secret.
