I suspect someone at AMAZON goofed up because this 4-CD set is priced at $16.97. Other classical music sites are selling the same box set in the $40 range. I’ve been a fan of Claudio Arrau for decades. He’s a fine pianist with plenty of fire. But he can also play demanding pieces like Chopin’s “Impromptu No. 4 in G flat major Op. 51″ and make it look easy. If you love piano music, don’t pass up this deal. You’re getting four CDs of great music for the price of one!
