Pretty cool. You know, I found myself agreeing with just about everything he was saying in the article. If you want a career these days, the way they are going about it might be one of the best.

If you look at the standard bio for a string quartet these days, it tends to reveal just how soul-deadening the traditional approach can be. Studied with professors X, Y and Z at Famous Music School.

Have played at Famous Music Festivals W, T and F. There is no individuality there as the bio of every string quartet reads exactly the same. I kind of prefer Break of Reality.
