The Canadian pianist Glenn Gould had a storybook entrance into the concert world. A famous concert in Washington D.C. of highly unusual repertoire (for the time) drew rave reviews, and shortly thereafter an exclusive recording contract with Columbia, one of this country’s biggest labels. Gould’s first release should have left classical listeners cold; he chose to an abstract sleeping pill written by J.S. Bach for a student’s insomniac patron. But surprising everyone, the album became a best seller which has not gone out of print in 55 years.
