Guillaume Dufay. Missae Sine Nomine, Ave Regina Coelorum, Caput Clemencic Consort (vinyl Lps)

Chorus sine nomine, founded in 1991 by Johannes Hiemetsberger, is one of the most distinguished and innovative concert choirs in Austria. On this CD, the choir presents motets by Anton Bruckner. Bruckner simply called them sacred choruses, as the reason for their composition can usually be traced back to a liturgical occasion. The six works on the CD correspond to such liturgical interludes: Graduale (Christus factus est, Locus iste, Os justi, Virga Jesse), Offertorium (Ave Maria) and a hymn for the Good Friday liturgy (Vexilla regis). As an organist, Bruckner was admired above all for his improvisations. He was particularly admired for his high contrapuntal skills, in which he demonstrated his craftsmanship in fugue and imitation. The style of the fugal parts of his improvisations was based on Baroque patterns (such as Handel), while in other, more imaginative parts the tonal language of his organ playing became increasingly typical of Bruckner. Martin Haselböck establishes this connection to Bruckner with his organ improvisations.

Vivaldi, widely known as a violin virtuoso and composer, wrote no less than 49 operas. This opera, set in the historical Olympic games, displays some fantastic arias. The Clemencic Consort, under the direction of Rene Clemencic, gives an authentically based performance with a great cast of singers such as Elisabeth von Magnus and Gerard Lesne.

Although known almost exclusively for his instrumental concertos and the spurious Adagio attributed to him, Tomaso Albinoni was mainly a man of the theater; he composed 81 operas and, late in life, made his living as a singing coach. However, the best efforts of posterity to catch up with Albinoni's operatic creations are significantly stymied by the fact that only three of his stage works are fully extant, the rest preserved only in occasional and fugitive fragments in the form of single arias and other bits and pieces. "Il Nascimento dell'Aurora" is a serenata – or more specifically, a "festa pastorale" – a kind of courtly entertainment not really meant to be specifically dramatic or compelling and, in this case, dealing with the birth of Roman goddess of the dawn, Aurora ….

Born in Venice, Sartorio composed 14 operas. He often made the long journey from Hanover, where he held the post of Maestro di Capella to the Duke of Brunswick, to compose and present new operas in his native city and recruit musicians for the German court. He is credited with introducing Italian opera to the Hanover court in 1672. Sartorio finally returned to Venice to be Maestro at St Mark’s where he composed sacred music, albeit not as much as the renowned Coffi might have been expected of him in that position.

These recordings illustrate the Vivaldi's genius in a way comparable to that of the Four Seasons or the Concertos of Opus 10, they are too, a fresh and delightful demonstration of the art of bel canto.

TESTORIDE ARGONAUTA (1780). Written for the court of Portugal, which was in the grip of an Italian opera craze that engulfed 18th-century Europe, this has a typical opera seria plot based on Greek mythology with extreme situations and graceful, expressive arias. The music may remind you of Mozart, but the composer's stature is actually closer to Cimarosa or Paisiello.

Famous as its title has become through Carl Orff's work of the same name, the original Carmina burana—a German manuscript collection of mostly secular songs, probably compiled in the early thirteenth century—is all but unknown to modern listeners. That it should be so is hardly surprising, since many of the pieces in the manuscript pose formidable editorial problems (inasmuch as they can be deciphered at all), and since virtually nothing is known about the manner in which they would have been performed and accompanied, nor about the circumstances under which they would have been heard. In short, it is improbable that any twentieth-century performance of songs from Carmina burana will ever come close to the original experience, and it would certainly be fairer to describe such modern reconstructions as the present one as little more than exotic entertainments loosely inspired by material from the manuscript, much as Orff's cantata is.

Fux was born to a peasant family in Hirtenfeld in Styria. Relatively little is known about his early life, but likely he went to nearby Graz for music lessons. In 1680 he was accepted at the Jesuit university there, where his musical talent became apparent. From 1685 until 1688 he served as organist at St. Moritz in Ingolstadt. Sometime during this period he must have made a trip to Italy, as evidenced by the strong influence of Corelli and Bolognese composers on his work of the time.
