It's no.3 on p.10 in of the Collected Works of Gaspar van Weerbeke, one of the most acclaimed composers of the Josquin generation. So apparently the composer is misattributed on the recording.

Attached is the copy I just downloaded.

Just for the fun of it!

Cool shirt, but it just wouldn't work in Berkeley! And across the Bay, the Stanford Josquin Project presumes to be on a first name basis with Weerbeke.

The CPDL Alma Redemptoris/ Ave Regina caelorum by Josquin seems to be a fairly secure attribution.

I understood. The NG Weerbeke worklist has rather few conflicting attributions, though it's hard to say whether that's because his name attracted fewer misattributions in his own day or whether he is yet to receive the scrutiny of the giant-killers who have dramatically revised the Josquin & Rembrant canons.

By the way, besides the Ave Regina in question, Gaspar has a Ave regina celorum, mater in the cycle Quam pulchra es and a Ave regina celorum, ave in the cycle Ave mundi domina.

I was not familiar with Weerbeke. Lovely, thanks.
