I agree with the music fan from Stockholm. This is a superb performance. Even the least known and least played of the three sonatas (no. 1) comes to life in the hands of Mr. Kovacevich. Compared with other popular performances of these works (for example, by Brendel, Ashkenazy, O'Conor), superlatives apply to Kovacevich's performances. The words unsurpassed, brilliant, magnificent, exhilarating, and dramatic come to mind. If you think you have heard these Beethoven sonatas before, think again. You will change your mind after listening to Mr. Kovacevich. In agreement with the reviewer from Sweden, I also find the recording a little shrill at times. The sound of other recordings (e.g O'Conor) is better. Also, the accompanying booklet needs rewriting.
