The abundant legacy of Gustav Leonhardt's recordings for Telefunken's Das Alte Werk series invites us to follow his trajectory as a performer from the early 1960's onwards, a time when the new codes of early music had yet to be invented, when their success depended above all on the strength of conviction of the performer. Leonhardt's was strengthened by dialogue: with a range of partners whose variety defies all preconceived ideas, with ancient instruments or modern copies of all types, with repertoires as diverse as Byrd, Purcell, Rameau, Johann Sebastian but also Carl Philipp Emanuel Bach. Not forgetting the 1970 Monteverdi LP, which has never been reissued since. The image of a pope of early music isolated in his tower and frozen in a school style does not last long after listening to this historical sum, extended here by the later series of recordings under the Virgin Veritas flag.
