Regarding the Babadjanian biography: You wrote "No problem for copyright". But actually this is a carbon copy of the biography from the Naxos wesite, see http://www.naxos.com/composerinfo/49.htm
So I am not sure if we can just use this without any changes (as I rather hoped...).
Regarding the 'Brain' composition:
First, we are very sorry to hear about your wife's condition. You write she cannot walk but hopefully she is ok otherwise, physically and mentally ? I assume it was a brain tumor, has it been permanently removed ? If you are taking care of her, in addition to being such a great composer and pianist, you have our deepest respect and sympathy.
I much admire this composition. It is not easy to grasp, and will need repeated listening, which I will certainly do. But even after one hearing, I love these dark and ominous sounds and the sometimes surrealistic quality of the music (which I also found in your etude). It is a shame it is compressed to 48kbps as it rather sounds like a midi recording (but it is recorded by an orchestra, right ?).
To have this on the site will be a novelty, but I see no reason why not, as you are listed as a pianist. I think we should also make an exception for your midi etude recording, on the condition that you promise to give us a real acoustic recording one day. This should not be a great practical problem with quality portable MP3 recorders now being on the market for an affordable price.
