Eileen Farrell (13 February 1920 – 23 March 2002) was one of the finest and most versatile singers that the United States has ever produced. She began her career as a radio singer, the star of her own program, Eileen Farrell Sings, which ran from 1941 to 1945, which offered a wide range of music from the pop songs of the era to opera. In the 1950s and early 1960s Farrell was involved with the legendary Bach Aria Group, originally founded in 1946 by scholar and philanthropist William H. Scheide, which consisted of a quartet of singers (which in Farrell’s time included tenor Jan Peerce, alto Carol Smith, and bass Norman Farrow) and a group of the most gifted instrumental soloists of the era (including oboist Robert Bloom, flautist Julius Baker, and violinist Maurice Wilk). Alongside their pathbreaking performances, they made a series of celebrated recordings for RCA and American Decca, excerpts of which are heard on this episode. Though Farrell had a huge voice, it was well-suited to the music of Bach, which she performed with suppleness, flexibility, poise, and power. Farrell may have been but a reluctant opera star, but her most long-lasting musical love was probably the Great American Songbook. Years beyond her official retirement, indeed well into her 70s, she continued to record both standards and less-familiar material, and her recordings of pop songs from the 1960s through the 1990s – buoyant, playful, perceptive, often heartbreaking and always deeply musical – form a substantial component of her recorded legacy. In this episode I contrast her performances of these two disparate styles of music, recorded over the course of forty years, to shed light on her continuing supremacy among American sopranos.
