Just a notice to inform Forum members of a recording from 1996 by Hartkeriana (now available online) of the first and maybe the best recording made by this ensemble. Among other chants, the Haec Dies from the Paschal week is recorded as a single track with verses of all the days in the week following Easter Sunday (sung by a tenor soloist, John van Halteren) - rather a unique item in the recording - almost 14 minutes. https://hartkeriana.hearnow.com/psallite-sapienter-psalms-of-praise-and-penitence
