Classical music fans are mourning the loss of Christa Ludwig, the beloved German mezzo-soprano celebrated both for her versatility and the warmth of her voice. She died at her home in Austria on April 24 at age 93.

Ludwig embraced a broad range of opera roles, with her silken tones, from the battered mistress Marie in Alban Berg's modernist Wozzeck, to the cheeky pageboy Cherubino in Mozart's Marriage of Figaro.

For decades, most of what jazz scholars have known about the late, Philadelphia-based pianist and composer Hasaan Ibn Ali came from a single 1965 album – The Max Roach Trio Featuring the Legendary Hasaan.
