Ive seen Devils Interval twice. I thought they were very good technically,they got all the right notes etc, but there was no "soul" or warmth and I didnt feel as if I had had an "uplifting" experience or "emotionally touched" by anything they performed. I would not be bothered about seeing them again.

Ive seen 422 twice, and came away thanking God I had lived to see them - so energetic, so warm and empathic with the audience and cant wait to see them again.

I understand from info in these threads, that one or two of them did the degee, and all of Devils Interval did the degree - correct me if Im wrong there.
so the conclsuion based on these few facts is as has also been stated in this thread - if you are a good musician, you will be a good musician, if not then all the degrees in China wont make you one.
But again, like Dazbo says , a degree is a degree, there to get people to think, not to make money.
This is aa very difficult subject - it makes my head spin!!
