This, Vivaldi's very first opera, was premièred in Vicenza in 1713 and was an instant hit. The story is a relatively uncomplicated one by the standards of Baroque opera, of amatory pretences and misunderstandings: it has been admirably summarised by Eric Cross (who has edited the work) as a 'light-weight, amoral entertainment in which the flirtatious Cleonilla consistently has the upper hand, and gullible Emperor Ottone (a far from heroic figure) never discovers the truth about the way he has been deceived'. The score proceeds in a succession of secco recitatives (with just a very occasional accompagnato) and da capo arias – which the present cast ornament very stylishly.

Kalevi Aho is one of those rare creatures, a living composer whose self-effacing nature - he looks endearingly owlish in all his publicity photographs - conceals a consistent and enchanting musical talent. After 40 years of large-scale works he has entered a much more intimate phase with Rituals, which consists of three separate pieces designed to be performed as a single concert. The work was premiered and recorded by Storgårds and the Lapland Chamber Orchestra in November 2007.

There are four surviving church cantatas by Bach for solo alto voice. One, Wiederstehe doch der Sünde BWV54 was probably composed in 1714. The other three were all written in 1726, after Bach had taken up his appointment at St. Thomas’s, Leipzig, and so it is a sensible idea to group them on one CD.

Joseph Martin Kraus was one of the most talented and progressive composers of the 18th century, and regarded by Haydn as one of the only two geniuses he knew, alongside Mozart. Following the successful audition of his opera Proserpin, Kraus became closely associated with the court of Gustav III in Stockholm. The highly dramatic Begrafnings-kantat overture was the composer’s emotional response to the assassination of his sovereign. The vocal pieces include works performed for the first time in over two centuries, ranging from Italian concert arias to rare survivals from the Royal Dramatic Theatre.

The Magnificat and Gloria, written in 1822, are Mendelssohn’s first large-scale works which he composed for reasons other than study purposes. The influence of the intense cultivation of Bach by his teacher, Carl Friedrich Zelter, and the Berlin Sing-Akademie are clearly evident, as in the later chorale cantatas. The masterful 19-voice motet, Tu es Petrus, which Mendelssohn gave his sister as a birthday present, he had planned to publish as his very first sacred work. Frieder Bernius and the Kammerchor Stuttgart present a further addition to their model, prizewinning CD series of Mendelssohn’s complete sacred works.
