Recorded live in Amsterdam in 1977. Booklet with texts in Latin and translation, liner notes and photographs from the performance. Thornton and Bagby formed the vocal group Sequentia a year or two later, specializing in medieval music, and this album is effectively the debut record of that group, though under a roundabout name.The booklet in my copy is eight pages, not six, and with text running onto the inner gatefold, totalling ten pages (in German with English and French translations)
