NEW YORK — Chick Corea took the unusual step of releasing four major recordings last year covering a wide gamut of music — everything from solo piano improvisations to a concerto for jazz quintet and chamber orchestra. "People in the music business say don't make too many records because they'll compete against one another," Corea said. His album "Hot House," the latest chapter in his 40-year partnership with vibraphonist Gary Burton, has three nominations — best jazz instrumental album, improvised jazz solo for the title track and instrumental composition for "Mozart Goes Dancing." "Further Explorations" on which he pays tribute to major influence Bill Evans and is joined by Evans trio alumni drummer Paul Motian and bassist Eddie Gomez, was nominated for best jazz instrumental album and improvised jazz solo for "Alice in Wonderland." – AP
