Especially in the newer regions of experimental music and avant-garde jazz, the internet offers great opportunities for promoting material that is difficult to get released by established labels. The self-promotion often coincides with a willingness to share the material freely, as a matter of necessity or of principle.
Here are a few "labels" from which you can download the material. The music is often minimalist, soundsculptures with electro-acoustic elements.
Zpoluras is the blog on which you can find different new bands, albums and links to the new labels and music. Several of the album are available for free download too.
Paulo Chagas and Bruno Duplant - Complicity (self-published, 2010) ***½
Rhizome Records is created by French bassist Bruno Duplant, and has released one album so far.
Astula Democratica - Illusio (Rhizome Records, 2010) ****
Array is a "label" founded by multi-instrumentalist Massimo Magee, with the telling mission statement "When we are no longer bound by the constraints of time, the past-present-future, the beginning and end, it is then that we must turn to concepts like arrays that allow us to consider all the endless possibilities that would be available to us simultaneously in that one endless moment outside of time".
Tim Green, Massimo Magee, John Porter - Of An Evening (Array, 2010) ***½
Zero Centigrade - I Am Not Like You (Twilight Luggage, 2010)
The challenge of breaking boundaries is that, while deconstructing the known, you have to create something new in the process, something that is worthwhile listening to - and not just fun to play.
You will need open ears for much of the material on these albums, and even if not everything works, some of the adventurous parts integrate moments of great playing - and listening - and we can only applaud the musicians for their vision and audacity in shifting boundaries, both musically and in terms of publishing their music.
