For the present, Pomerium's new CD is an indispensable part of the record collection of anyone who is interested in the music of Du Fay, since it includes a recording of his Recollectio Festorum Beate Marie Virginis, discovered just over two decades ago. The work consists of a series of pieces in plainchant written in 1457 by the Flemish composer for the institution of a new feast in the cathedral of Cambrai. This very rare example of plainchant is followed by the Magnificat sexti toni, a way of concluding the Vespers, and another four polyphonic compositions: the motets Nuper rosarum flores, Alma redemptoris mater, Letabundus and Ecclesie militantis.
