"Orchestral Excerpts" series
Do you know about this series?
Five of the series (flute, clarinet, trumpet, trombone, and tuba) have been converted to downloadable MP3 format, at $9 an album or around 99 cents a track -- which seems a bargain to me.
I downloaded the trumpet, trombone, and clarinet albums recently, and can tell you they provide a wealth of material for anyone who's serious about modeling orchestral instruments.
They make a nice supplement to the freely downloadable Philharmonia Orchestra demos
that get mentioned here from time to time.
I hope Amazon will convert the rest of the series to MP3 soon.
