(early-/ mid-60s recording, featuring Julius Katchen soloist).
It is not surprising that Side One's "Variations & Fugue on a Theme by Handel", by Johannes Brahms, was premiered in a performance by Clara Schumann : her husband, Robert, had mentored the young Johannes to a considerable degree, and for Brahms, one of the worst periods of his life, was witnessing the later mental breakdown, of Robert Schumann.
These were composed in 1861, when Johannes was 28.

It was the Austrian pianist, Karl Tausig, who inspired Side Two's "Variations on a Theme by Paganini", partly because Johannes was so intrigued by Tausig's virtuosity (Karl Tausig was also a prominent admirer of both Richard Wagner and Franz Liszt).
