I think they are doing that, and they've been quite clear about it, is because they are looking for a guitar "star" they are looking for stage presence. The odd chap who played with his teeth had the persona but he didn't have the chops - they said that when they excluded him but he was a performer. Same for the kid he had the star part but he didn't have the technique. Huey said they would differentiate who would be a stage performer and who would be more suited to a studio type setup. That's what I thought.
Also the expressive Classical guitarist the first girl in London. Helen had quite obviously already seen her play by the way she referred to her in the familiar fashion. That girl is quite obviously already known to her as a good player.
But yes rock was poorly represented and I didn't see one who could play better than me tbh. Yes some could sweep pick quicker but I don't think they could play better. But the other styles, of which I also play, I saw some playing that was well beyond what I could ever achieve. I think it is good they've put some of the young ones through because I think they will improve massively with the coaching, as kids do, and you may see a far more specific and focused performance as time goes on. The one rock player to actually come across well was the chap who defied expectations and didn't a laid back harmonic arrangement. It was a clever move and tbh whilst I love the likes of Vai and Satch - it's not their technical ability that marks them out it's their ability to create the melodic component. TBH I find most shredders are like watching Theo Walcott play for England - yes the lad can run quick but as a footballer allround he's utter ****.
I largely agree with what the judges have said so far. I was disappointed we didn't have any flamenco, not a great range of jazz, blues non-existent, only one slide, etc. So many styles people aren't playing it seems.
