Alonso del Arte has started the IMSLP Orchestra! From the IMSLP Forums:
I would like to start the IMSLP Orchestra, and to have them make the world-premiere recording of the Symphony in C major by Franz Asplmayr. It would be like the YouTube Orchestra, except the players would not necessarily have to meet, and some players could play multiple instruments (e.g., a bassoonist could play both bassoon parts). These would all be synchronized by a mechanical playing of my figured bass realization; each player would listen to the continuo through headphones, which would hopefully not bleed into the recording of their playing. Later on a skilled harpsichordist could give a less mechanical performance that would be integrated into the finished recording…. More
NB Franz Asplmayr, 1726-86, was an Austrian composer and violinist, best known for an opera on Greek myths.
