Following his critically acclaimed recording of Ludwig van Beethoven's complete piano sonatas and the Diabelli Variations from 1992-1996, pianist and conductor Alfredo Perl is now scaling this summit of classical-romantic piano music for the second time. His concept, developed through intensive artistic and pedagogical examination, now applies to the whole"Beethoven, i. e. all the surviving original compositions for solo piano, including the works for piano four hands. The recordings, which in the case of the piano sonatas are based on the edition by Jonathan Del Mar, will be released in three CD boxes and will also be available on all relevant platforms in Dolby Atmos as well as stereo downloads. The edition is structured according to the three creative phases 1791-1800, 1801-1814 and 1816-1825, corresponding to the periods in which the main works - sonatas, variations, bagatelles and outstanding individual pieces - were composed. The last box also brings together the youthful works from the Bonn period, the dances and other individual pieces as well as the works for four hands. This not only allows the development of the piano composer Beethoven to be traced directly, but also reveals the relationships that exist with his role models and successors Bach, Haydn, Mozart, Chopin, Liszt, Schumann and Brahms. The sonatas are accompanied by twelve important variation works (WoO 64-66, 68-73, 75-77), which are still rarely heard in the concert hall, as well as the Allegretto in C minor WoO 53, the two Rondos op. 51 and the Capriccio "alla ingharese" op. 129, which became famous under the title "Die Wut uber den verlorenen Groschen". The opening box contains the first 13 sonatas (op. 2 no. 1-3; op. 7; op. 10 no. 1-3; op. 13; op. 14 no. 1-2, op. 22 as well as the short sonatas op. 49 no. 1-2) with which Beethoven revolutionized this genre after moving to Vienna.
