Ahh, I see what you mean... :-/
I assumed the post was speaking of seeking a possibly more authentic contrast to "Mediaeval Babes".
Interesting question about authenticity though. If there has been an unbroken continuity in the performace of Rennaissance composers works (?), my guess would be (bar some minor deviance as a consequence of subtle changes over time) that what we hear performed now, would not be vastly dissimilar to what we would have heard performed then. That assumption may be incorrect of course.
