Mmm... just listened to Andy McKee and Gareth Pearson. No real form there, for me, once you've got past the technical brilliance - and brilliant it is. McKee in particular sounds as though it's a continuous loop of ambient music - which is maybe what he wanted. Can you whistle it five minutes after hearing it? Not that that's the ultimate test of course - but, to be honest, I'd rather have 2.5 minutes of Cliff Gallup blasting out some '50s rock'n roll behind Gene Vincent.

The first blues I ever heard was Lead Belly singing "Grasshoppers In My Pillow" - one of the most moving and simple bits of 12-string guitar playing ever. And Graham's re-working of it into "Leaving Blues", with it's amazing riffs, has far more flesh on the bone than some of the rappers and tappers of today - in my opinion, of course! :-)

As for comparing these styles with someone like Graham, it's worth remembering that, in his day, DG broke the rules, doing stuff like no-one had ever done before - which is why it still resonates today, around 50 years later. Graham wasn't a prolific composer, but the approach he took to the guitar was as revolutionary then as others are now.
