MacLeod's description:

Genre: Classical
Length: 7:17
Instruments: Orchestral - Flute, Violin, Viola, Cello, Harpsichord

Bach. Violin, 2 Flutes (standard C Flute in this case), a mess of strings, and harpsichord. The primary violin is obviously sampled in a few of the faster passages, but the sweet tone shines through nicely on the slower notes. This is my first attempt at a Brandenburg... I suspect I'll revisit this one after I get a few more recorded. Still, it is probably the best free and digital recording available. 008
