With this fourth album - which features one of the best loved of all of Beethoven's works, the 'Moonlight Sonata' - Ronald Brautigam reaches the year 1800. Ronald Brautigam's ongoing cycle on the fortepiano of Beethoven's piano music has been an ear-opening experience for many a listener, as testified by the glowing reviews. The first volume (BIS-SACD-1362) raised the expectations of the critic in Fanfare for 'a Beethoven piano-sonata cycle that challenges the very notion of playing this music on modern instruments, a stylistic paradigm shift'. The reviewer on website klassik.com called Volume 2 (BIS-CD-1363) 'absolutely extraordinary' and stated that 'if this high artistic level is maintained, this Beethoven cycle is set to become an interpretative milestone. Only a select few are able to arrive at such a perfect mix of youthful fire and technical mastery.' And the recently released third instalment, (BIS-SACD-1472) has fulfilled the promise of the previous discs: 'Beethoven the revolutionary comes closer than ever in Brautigam's fiery interpretations', wrote The Times (UK) and the critic on the website MusicWeb International stated that 'these are once more thoroughly exciting, utterly musical performances that make you hear this music afresh.'
