Dear friends,
first of all for my no correct English. I'll try to do better, if it'll will be possible.
On my "little" website
http://vitoliuzzi.altervista.org in Music section, you can downlaod, if you are interested in, the all four movements of Nino Rota "Divertimento Concertante" written for Franco Petracchi, and that I've played live during an Italian Tv recording. I know. The performance is not so good, the audio has been extracted from a simple videocamera and it's also in mp.3 (because I didn't like the original one of the TV Broadcasting). But if I point out it, the reason is simple: to develope a very beautiful and contemporary concert for db. and orchestra (or piano) and to help some students to get over some difficulties.
Thank you and my best regards.
Vito Liuzzi - (Italy)
p.s.: I've played on a "Donato Rubino 2005" double bass (a 2/4 size copy of a Tarantino, diapason 104, and a Slaviero bow by Cremona, Obligato SOlo STrings).
