Though he didn’t record Chopin intensely throughout his Warner career, Claudio Arrau had close affinities with the Polish composer. He performed an étude in the program of the very first recital he gave at the age of only five, and he was the first composer he put on record in 1921. Here is a beautifully remastered version of the complete Études, Op. 25, with the rare Allegro de concert.
