As a result of the the pandemic, Daniel Heide challenged himself to re-discover Beethoven's sonatas.

"In each volume of my complete recording of the piano sonatas of Ludwig van Beethoven, I have clearly chosen the order of pieces with autobiographical criteria in mind. Over the past 15 years, my work as a pianist has increasingly migrated toward music-making in partnership with others. Although I started out mainly as a chamber musician collaborating with instrumentalists and singers, the focus has increasingly shifted toward duo recitals, primarily vocal recitals on a worldwide scale - but I never could have dreamed that such appearances would become so frequent that they would allow me to earn a stable living. Whenever I was asked what became of my solo playing, I had to answer with a shrug, explaining that I needed a sort of sabbatical to let me practice solo repertoire undisturbed before I started giving solo piano recitals again. Then, covid struck. All of a sudden, I had time on my hands. (Excerpt from the Booklet nores by Daniel Heide)
