Celebrating his half-century as a Decca artist, as well as his eighty-fifth birthday, Sir Georg Solti here offers a nicely autobiographical collection of three sets of variations: the Peacock Variations of Kodaly representing his Hungarian roots, the lively Paganini Variations of Blacher a recognition of his years as German citizen, and finally a tribute to his unique Britishness in Elgar's Enigma Variations. The disc is also a tribute to the Vienna Philharmonic and Solti's special relationship with that orchestra, with whom he recorded these live performances in the Musikverein last April. You have only to compare this warmly expressive, subtly nuanced, and deeply felt account of the Elgar with Solti's earlier Chicago version of 1974 to appreciate not only the quality of this great Viennese orchestra, but the way in which Solti has mellowed over the last two decades.

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.
