Johann Sebastiani's name no doubt will be familiar only to a few certified music experts. Born in Weimar in 1622, Sebastiani spent a good many years of his life in Konigsberg, where he arrived around 1650 and later was appointed court chapel master. He composed countless occasional works as well as a St. Matthew Passion (1672) – a welcome addition to CPO's picture of Lutheran church music and a work closing a gap in the history of Passion settings between Heinrich Schutz and Johann Sebastian Bach. Stephen Stubbs, Paul O'Dette, and their Boston Early Music Festival Chamber & Vocal Ensemble have fond memories of Bremen, where they have recorded in the radio broadcast hall on various occasions and produced Marc-Antoine Charpentier's Baroque opera La Descente d'Orphee aux Enfers, for which they won a Grammy Award in 2015. Their current release featuring Johann Sebastiani's St. Matthew Passion pays tribute to Konigsberg's music culture and to the composer who was one of its central representatives.

This CPO issue of Johann Georg Conradi's 1691 opera Ariadne is based out of a revival of this obscure work produced in 2003 as part of the Boston Early Music Festival. One might be surprised to see the name of Conradi above the title of such a large opera set – has anybody really heard of this guy? What is up with this opera?
German Baroque opera has spent centuries in the shadows. At one time this entire historical genre was considered of only marginal value when held up to the shining example of George Frideric Handel. Closer examination of the topic reveals that this was one man's opinion, namely that of nineteenth century musicologist Friedrich Chrysander.

The prizewinning Boston Early Music Festival, joined by the choicest soloists, once again presents a spectacular Baroque opera discovery with Christoph Graupner’s Antiochus and Stratonica. Graupner composed the musical play L’Amore Ammalato, Die kranckende Liebe, oder: Antiochus und Stratonica during his time as the harpsichordist at the Gänsemarkt Opera in Hamburg. The core subject of the opera is the love of the Seleucid prince Antiochus for his stepmother Stratonica. This match brings with it highly dramatic moments as well as deeply sad ones inasmuch as Antiochus is supposed to have an incurable illness – but then at the end three old and new romantic couples appear on the stage and everything comes to a happy ending.
