We have modern examples of ensembles on similar instruments in the Venere Quartet, the Kings Singers, and Piffaro, when they are on recorder. For mixed ensembles we can look to Piffaro, Baltimore Consort, and many others.
Frankly, I find hour-long programs on similar ensembles deadly boreing, much prefer the varyance of a mixed ensemble. Voices, even ones that blend well, still have individual characteristics ones mind can pick out. I recall working with one composers Missa, very polyphonic for voice. I had prepared a piano score from the open vocal score as we were blessed with a piano and player that week, 5vv with the inner parts doing a lot of crossing, I wasnt sure my rendition would prove suitable for our pianist, but she proved up to the task. Sadly the polyphony got lost in the piano, and revealed the masterpiece for voice was deadly dull on piano, basically one chord for most of 32 bars. -- Dana S Emery To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
