The Goldberg Variations from J. S. Bach, played by Glenn Gould in 1981 (first video) and 1955 (second video). 26 years before.
“One of the most important classical recordings of the twentieth century (on any list) is oddball Canadian genius Glenn Gould’s 1955 recording of The Goldberg Variations, a keyboard suite by J.S. Bach, master of the Baroque. Connoisseurs often point to his 1981 recording of the same work as better than the 1955. Either way, you won’t go wrong. Sublime and stirring, the opening movement of the work is as soulful and beautiful as you could possibly want.” – Primermagazine.com
I knew so little about Classical music that I thought The Goldberg Variations was something the Goldbergs did on their wedding night.
