The last three piano sonatas, which Beethoven composed between 1820 and 1822 parallel to his Missa solemnis, have a very special aura. They are regarded as a testament in which the composer summarised his sonata oeuvre once again in the most concentrated form, with a spiritual brevity, but also gave new space to the lyrical, the songful, and in no way renounced passion. Works of reflection and outlook, also of melancholy and consolation. Elisabeth Leonskaja recorded the Trias for CD in 2009 and performed it repeatedly in concert. In 2011, after one of these evenings in London, a critic heard her interpretation of the finale from Opus 111 as an „ascent into musical nirvana“, as music-making „that makes the world a better place“.
