in the Colloquium packet for 2019, under polyphonic choirs, I see this (my emphasis added) "The choir will sing motets by Palestrina and Brouwers as well as polyphonic Mass parts by Victoria (Kyrie and Gloria from Missa quarti toni) and Palestrina (Sanctus from Missa aeterna Christi munera) ."
Motets by Brouwers? Where are they to be found these days, I wonder?
I think you mean the 2018 Colloquium packet, which lists the works you mention. Also, Brouwers led the Polyphony I choir that year - and (fixing something I missed before) he composed the O sacrum convivium that was sung at Communion in the concluding Saturday Mass (pp. 214-216 of the booklet).
