Steve Coleman and The Secret Doctrine is a sort of small version of The Mystic Rhythm Society. It is made up of completely different members and it is a group that is just starting and is in its experimental stage. The group's goal is sort of a combination of the directions of Five Elements and The Mystic Rhythm Society but usually the music is more complex. It helps a lot when there is a common experience but this common experience alone does not mean an individual musician will relate to the music in a way that is comfortable for me and the other musicians already in the group. You have mentioned that it is very difficult to find musicians who are capable of attaining the level of concentration and facility necessary to produce music associated with the M-Base concept.
Most professional musicians have plenty of facility.
It is difficult to find musicians and the difficulty has to do with a difference of conception of life first and music second. As I've stated before, the M-Base concept is not a musical style, but a state of mind. There are many many different ways of being creative and just because two musicians are both creative does not mean they will be able to make music together. Anthony Braxton once said something to the effect that musicians in the Afrikan Diaspora seem to be one step ahead of everyone else in music, and once they develop a new musical concept, they abandon it and move on leaving others to pick up the ideas that they had left behind. At any rate I don't believe that this is always the case, as a matter of fact, nothing is always the case.
