Whenever this question is posed, I have to ask: relevant to whom? While there may be a overall feel of the times we are in (like, a pressure cooker), and in a sense we are all in the same boat, there is just such a mulitplicity of perspectives, needs, and levels of understanding and personal development that I can't imagine any one approach to music encompassing, expressing, or reflecting it all. So if music is a mirror, then the current scene should be fractured, all over the map, suffering from information overload, and lurching both forwards and back, as is our world. Alex Grey gives an interesting analogy. In ages past, he says, art could be seen as a game, with clearly defined rules, and different "teams", or schools, trying to create masterpieces to score points. Today, the art world is like a field where everyone has their own ball, and is running wildly in every direction. Does that sound like the current state of jazz?
I can give examples of the music that is relevant to me, but that is only music that is meaningful to my particular journey through life. Two nights ago I was up late, listening to The Lark Ascending by candlelight. Last night I was grooving with a friend to Monday Michiru and Ursula Rucker, (courtesy of J. Sangrey), before working on some of our own music. Before that, I was enthralled by
clip of Luciana Souza, who is someone speaking to the NOW as I feel it.
What will influence the musicians of tomorrow will be the events of tomorrow. 15 or 20 years from now, we could be experiencing a very different societal arrangement. Things may have to be restructured on all levels due to the consequences of climate change, peak oil, dwindling resourses (especially water), and the like. Who knows what shape that will all take, and how it will effect the artistic communities that have been built up in the current era? But, as Sangrey and I have been discussing -- keep an eye on women (like Michiru, Souza, Geri Allen, et al.) to be stepping up to the plate with an answer.
Just my opinion.
