Legendary Cuban trombonist Generoso Jimenez, who redefined the role of the trombone in Cuban music and Latin jazz, died Saturday (Sept. 15) in Miami of renal failure. He was 90.

The prolific and tireless Jimenez worked nearly to the day of his death. He is heard on Gloria Estefan's new Burgundy Records album, "90 Millas," where he was a featured guest.

With his trombone, Jimenez literally lived Cuba's golden age of music. He was a member of the original lineup of Orquesta Aragon and later joined Chico O'Farrill's band. He found his greatest success as trombonist for the great singer Beny More, who reworked the lyrics of his famous song "Que Bueno Baila Usted" and turned them into "Generoso, que bueno toca usted" (Generoso, how well you play), effectively immortalizing Jimenez's name among legions of Cuban music fans.

Indeed, in 2002, Jimenez released an album titled "Generoso, Que Bueno Toca Usted," which was nominated for a Latin Grammy. Jimenez left Cuba for Miami in 2003 and remained singularly active. One of his last public appearances was June 23, when he played with Cuban singer Isaac Delgado in Miami.

Jimenez is survived by six children. He will be buried tomorrow in Miami.
