Of the three polychoral works by Portuguese composer Estêvão de Brito (c.1575-1641) present in his Motectorum Liber the motet Vidi Dominum, for eight voices (SATB+SATB) was the only one to be recorded in CD until recently. The other two works, also for eight voices, are O Rex gloriae, a motet that I have been writing a lot, and Dum complerentur. The motet has the indication In die Trinitatis et Omnium Sanctorum that is, it was destined to the Sunday after Pentecost and the Feast of All Saints.
The only recording of this work is by Pro Cantione Antiqua in their pioneering recording of Portuguese polyphony edited in the 1984 triple-cd Voces Angelicae. Although vocally old-fashioned, this is still one of the most important recordings of Portuguese polyphony not only for the quantity of works but also because, besides Brito, it also features only recordings of works by Estêvão Lopes Morago like the beautiful six-part motet Commissa mea pavesco and Filipe de Magalhães. Another interesting feature of this recording is the subtle use of the baixão (dulcian?), doubling the bassus part.
