Ha no just great playing and arrangements. I’ve heard so many Piazola renditions that have great technique but somehow feel dry and more of an exercise or a marketing ploy. Yours was very emotional and vibrant. You obviously enjoyed it! I’d like to know more about the arrangements. Who scored that?
I have been making arrangements for about 40 years now. For 30 years I was the leader of an accordion group in Antwerp, Belgium and quickly realized that in many cases existing (commercial) arrangements simply were not good enough. So I started making my own, specializing in arrangements for "smaller" ensembles (mostly from 5 to 10 players) but sometimes for smaller ones (2, 3, 4) or for larger orchestra. As this is not my main job I am doing everything for free. I make all my arrangements freely available from
https://www.de-bra.nl/arrangements.html, except when it is a recent work and the copyright-holders object. (So far that has happened only once.)
I mostly just make arrangements without a specific ensemble or orchestra in mind, but I did make some specifically for a group I played in, like the quintet ARTE, the quintet Kwintessimo, the orchestra Accordeana or the Dutch Symphonic Accordion Orchestra (NSAO).
For the past few years I am also trying to catch up with playing and recording. Ideally I want to have a recording (not necessarily by myself) to illustrate each arrangement. I think I'm currently at about 2/3 done: around 80 recordings done, for a total of around 120 arrangements.
I also publish the arrangements of those compositions that are in the public domain on imslp.org (the Petrucci Music Library), which means that the composer died more than 50 years ago (public domain in Canada and some other countries) or published more than 95 years ago (public domain in the USA).
