If you have ever wondered what William Wallace would sound like as the front man for a booming stadium rock band, then Scottish rockers Twin Atlantic's upcoming performance at Oppikoppi next weekend may be a good place to find out. While they are not gimmicky enough to don kilts and belt out songs about "the bloody English", the band's lead singer does still manage to sound like St Andrew's Cross set to music."When we were earning our stripes people used to view my accent as taking a big risk but so far it has worked out alright."There is nothing I can or want to do about it," said the man behind the brogue, Sam McTrusty.Despite getting their names on the map with their visceral and angst-laden debut EP Vivarium, those stripe earning days were not the happiest of times."It is almost like we were really, really angry when we did that album. The odd part is that I'm not really sure why. Maybe we just had unbridled passion, but it made the album feel disjointed. We've since learnt to harness that and make our music better," said McTrusty.The harnessing he is referring to involved the band veering sharply in the direction of bands like Pearl Jam, Muse and Royal Blood. Where Vivarium was a full-throttle, fire-breathing offering to the gods of punk rock, their later albums, Free and The Great Divide, have toned the angst down and scaled up traditional hard rock elements of their sound.They are now the kind of band whose music would not sound out of place in a climactic action scene from Terminator.This evolution arguably has something to do with their huge popularity on the British festival scene and the fact that that scene is gut-punching new life into stadium rock."We grew up on bands like Pearl Jam and so that is all we really wanted to play."I think the resurgence of stadium rock has brought a bit of realness back to the genre," McTrusty said.How "real" the genre may be is something fans and hipsters can sit around a dusty Northam fire discussing until the beer runs out.What is certain, however, is that a small farm in Limpopo is about to be invaded by Scots and the denizens of the dust bowl are in for a wild time.Twin Atlantic will be performing at Oppikoppi on Sunday August 9 and in Cape Town on August 7.
