Mogwai’s Stuart Braithwaite has got into a beef with former Test Icicles member Rory Aggwelt’s new band.

The guitarist started the battle of words by leaving a message on Rat: Att: Agg’s myspace page slamming their authenticity as a band.

It read: "Guys, seriously what the fuck is going on here? I keep hearing your song on MTV2 at night and i'm confused. is it a JOKE? I know i'm getting old but am i missing something? Is there an existential element that i don't get? I like the guitarists clothes but the singer needs medical help. Is it a pastiche on bob the builder? I think it is but the thought scares me."

In response, Rat: Att: Agg have posted a bulletin reading: “that's pretty funny, I used to like mogwai, I bought 10 Rapid when I was 15 and saw them play shit loads of times (saw them supporting pavement once which was amazing) it's just a shame they continued to write the same song over and over again for the next 10 years. Cheers Stuart, I'm glad we confused you, I think you need it.”

Let battle commence!
