Henri Adam de Villiers on Radio Courtoisie from just yesterday, as it happens (I saw a notice on his Facebook page), who spoke about the music for the upcoming feast of Our Lady's Nativity; the page is here. It goes behind a paywall after a week.
'Listening' is of course an overstatement: I followed as best I could but my French isn't up to easily comprehending such a spoken text.
One of the composers he mentioned was totally new to me, Bartłomiej Pękiel (fl 1633-1670). German-born, evidently, but Polish throughout his professional life. A recording of his Missa pulcherrima ad instar Praenestini, according to the style of Palestrina.
He also composed what is, they say, Poland's "only church oratorio" (in the original sense of 'oratorio', is what is meant: a work for an audience eager for spiritual edification-cum-entertainment, as at the Oratory of San Filippo Neri at Rome), Audite mortales, on the great and terrible Last Judgment-- I've listened on Spotify (in that recording it's just over 13 minutes in length, from a 3 disc opera omnia by the ensemble Octava [the website is being recalcitrant, here anyway, but August 2022's calendar is there, confirming that they continue to perform] which I'm having to bite my tongue to keep from buying) but I guess it's not at YouTube. And his Missa brevis.
