I was so thrilled to discover "Music Minus One" a month ago while browsing on SheetMusicPlus. Finally I'm able to play a duet with primo/secondo accompaniment or a concerto with full orchestral accompaniment on CD.
One of my favorite duets is definitely Faure's Dolly Suite. I used to play this with my father when I was little and this just brings back sweet memories of good times. So I was very happy to find this available under the Music Minus One series which provides the complete score and an accompanying CD for both primo and secondo parts.
Yesterday, I had fun playing Le Jardin de Dolly (no. 3 from the suite), recording the primo part and then mixing in the secondo part from the CD. Quite pleased with how it turned out :)
This summer, I'm thinking it would be really neat to work on Mozart's Concerto in C+ KV503 with full orchestral accompaniment from the CD:)
