In Search Of Polyphonic Recordings By Good Choirs

I am looking to add a few CDs to my collection of Renaissance polyphony recordings. Can you help me? Here are the criteria:

1. Must have been composed between 1530 and 1600.

If most of the pieces on the recording are between those dates, we’re good!

2. No instruments, please.

Just FYI, I’ve heard all the arguments for and against accompanying Renaissance polyphony with instruments.

3. Lesser known pieces and composers would be appreciated.

I don’t desire another recording of Palestrina’s Missa Papae Marcelli.

4. Really, really good choirs.

If possible, no amateur choirs. Thanks!

5. Please don’t say Tallis Scholars.

While I admire many things about the Tallis Scholars, many of their recordings sound “top heavy” to my ears. In other words, the soprano lines are way out of proportion with the other voices. My concept of “polyphony” is that all the voices are more or less equal. I don’t like when the soprano section predominates. Somebody told me the director of the Tallis Scholars is married to one of the main soprano singers, but I’ve never been able to verify this. If true, maybe that explains it.

6. Don’t be shy!

Please let me know your suggestions in the combox below. Thanks! I owe you one!
