Although I couldn't have a chance to attend the concert, I too am interesting to know if there are any good transcriptions of Piazzolla's tangos for 1 piano 4 hands. Any pointers? Thanks!
Hi,I attended a concert just last week of an Italian pianist Cristiana Pegoraro and she plays a lot of his works. She has transcribed many of Piazzola's Tangos for piano. These are for 2 hands, however. On her website you can buy the scores for the pieces and also she has a CD of her performing the songs. She was quite good. It was so refreshing to hear a live performance of something different from the usual classics and she plays with much passion. She also does a lot with other Latin American and Cuban dance music as well as the classics. Hope this helps. https://www.cristianapegoraro.com/index.html
There's an amazing recording of Oblivion by the world's greatest accordionist Frank Marocco. It's on his CD Apassionata. You can get it on iTunes. Great song. It's inspiring.
