Haendel's major label recordings have earned critical praise. The Sibelius Society awarded her the Sibelius Medal in 1982. She said she always had a passion for German music. Her recording career began on 10 September 1940 for Decca, initially of short solo pieces and chamber works. In April 1945, she recorded both the Tchaikovsky and Mendelssohn concertos followed in 1947 by the Dvořák concerto. Her recording career spanned nearly 70 years for major labels including EMI and Harmonia Mundi. In 1948–49 she recorded Beethoven's Violin Concerto, with Rafael Kubelik conducting the Philharmonia Orchestra.
