The French division of the massive EMI corporation has released a compendium called Les Introuvables de Dietrich Fischer-Dieskau (EMI 68509, six CDs), and it contains so much outstanding material that one feels churlish complaining about what it lacks. But here we go. These six discs contain more than 125 lieder, ballads, cantatas and songs – primarily in German, but also in French, Italian, Latin and English – recorded mostly in the 1950s and '60s when Dietrich Fischer-Dieskau's voice was one of the wonders of the musical universe.

A beautifully-packaged 50-disc box set, released to celebrate the 50th anniversary of Deutsche Harmonia Mundi, one of the most important and adventurous early music labels. The set contains 50 classic recordings of baroque and ancient music, chosen to represent the breadth of this huge and varied catalogue and each disc is slip-cased with artwork replicating the original CD or LP artwork.

10 CDs mit Passionen, Messen und Motetten passend zur Osterzeit . Neben den beiden berühmten Passionen von Bach - der Johannes- und Matthäuspassion - sind weitere hörenswerte Aufnahmen enthalten. Die Passio Domini Nostri Jesu Christi von de Rore oder den Lamentationes Jeremiae Prophetae von Zelenka sind hervorragende und selten aufgenommene Werke, interpretiert von herausragenden Künstlern.

The Academy of St Martin in the Fields was founded in 1959 by Sir Neville Marriner and a group of London’s leading orchestral players. Originally formed as a small conductorless string group, it spearheaded the 1950’s Baroque revival.

With her almost supernaturally clear and agile soprano, Emma Kirkby has enchanted audiences ever since she first appeared on the Early Music scene in the 1970s. And as the art of historically informed performance has become more and more widely appreciated, so has her style of singing, to the extent that she in 2007 was included in a listing of ‘the 20 greatest sopranos ever’ made by the BBC Music Magazine. Throughout her career, Emma Kirkby has made a large number of recordings of a wide range of music. Released on the occasion of her 60th birthday, the present collection celebrates her collaboration with BIS, which has resulted in ten discs to date.

Known for her idiosyncratic performances of baroque repertoire and eccentric personal style, the German coloratura soprano Simone Kermes trained in her native Leipzig, with early successes including the International Johann Sebastian Bach Competition. Bach has not, however, figured prominently in her career since then – Kermes gravitated towards Vivaldi, Handel and the Neapolitan composers who wrote for the great castrati, such as Riccardo Broschi, Alessandro Scarlatti and Porpora. (She has recorded several solo albums of such repertoire for Sony, including Dramma, and Colori d’Amore – reviewing the latter, BBC Music Magazine described her as ‘a remarkable artist, charming, fascinating and boldly risk-taking by turns’).
