This past Sunday, we had a Solemn Mass and Benediction (with a Te Deum) in the afternoon at Holy Innocents (no Vespers this week) in thanksgiving for Fr. James Miara's 10th anniversary of ordination.
The choir sang Palestrina's Missa Papae Marcelli for the ordinary and the schola (including your faithful correspondent) the Gregorian propers. At the offertory, the choir sang Gregor Aichinger's Regina Cœli with accompaniment on lute and baroque guitar, causing a friend to quip, "That's the best guitar Mass I've ever attended." I'd embed a performance of the piece from YouTube, but I don't like any of them.
