A decade ago, the cellist Anton Lukoszevieze was reading Gene Santoro’s magisterial biography of Charles Mingus, Myself When I Am Real, when a brief mention of a forgotten, maybe even lost composition captured his imagination. Mingus’s String Quartet No.1 was performed for the first and, during his lifetime, only time at the Whitney Museum in New York in 1972. It wasn’t recorded. Lukoszevieze got copies of the sheet music from the Mingus papers housed at the Library of Congress in Washington DC and discovered that, true to form, Mingus had rewritten the rulebook, including a part for voice and trading one of a conventional string quartet’s violins for a second cello.
