Its incredibly impressive that you manage to switch key signatures to this degree without people hearing it. I love the piece, one of my favorite quartet works. Great job!
It's very nice but I don't think you can play it with 2 people. In the original piece, the crazy thing is these rythm changes, that feel so organic, hence the "Mad Rush" title. It's constantly evolving. Rhythm changes are easy when it's just a guy and his piano, but way too difficult to render in a spontaneous way when it's two players. Which is why this rendition feels too stiff.
I feel pretty sure that you will love this suggestion-it is truly exquisite, in every respect, it is: Glass, Etude no.6 played by the Davin-Levin Duo. I hope you give it a try-it's quite a short piece!
So this was sort of Phillip Glass approaching the Steve Reich? I also, in some of Phillip Glasse's piano etudes, I here Arvo Part. // I enjoyed the way they brought out the dynamics, the "breating" of the volume. There is a wonderful gentleness about it. Guys, if you are out there, please see my work with color-association and musical notes. I believe I have pinpointed certain emotions to distinct keys. With proofs! Great work, none-the-less.
