The original 1805 version of Beethoven's only opera is a high-adrenaline experience in the hands of the Belgian conductor and his period-instrument band, with Marlis Petersen in the title-role and Maximilian Schmitt as her imprisoned husband. From Leonore (1805) to Fidelio (1814) there were three successive versions of Beethoven’s opera, only the last of which has been in the repertory since the 19th Century. Going against tradition, René Jacobs has chosen to revive the earliest version, reworking the librettos and the spoken dialogue: a genuine tour de force, this still unknown Leonore forms an incomparable musical and dramatic structure requiring exemplary mastery on the part of both orchestra and singers. This landmark recording proves its case in every respect.
