"Some consider Arrau’s live Beethoven sonata performances superior to the studio versions. In the later sonatas, Arrau himself alluded to the fact that an improvisatory approach was required which was difficult to achieve within a recording studio. Of op. 111, Jonathan Summers says in his booklet note that ‘as we near the close...we realise we've been transported to another world by Arrau’. This 1960 Stockholm recording, with Arrau at his career peak, is extremely rare and has never been issued."
