TOMS RIVER, N.J. - Chris Connor, a smoky-voiced jazz vocalist who had numerous hits during a career that spanned more than 50 years, has died. She was 81.

Connor, who performed with several big bands and also had an extensive solo career, died of cancer Aug. 29 at Community Medical Center in Toms River, said Lori Muscarelle, her longtime companion and manager.

Connor was known for altering rhythms on ballads, using little vibrato - except on special occasions - and a husky, lush sound heard on hits such as "All About Ronnie," which she performed with the Stan Kenton Orchestra, as well as "Trust in Me" and "About the Blues."

She also performed with the Claude Thornhill Orchestra and sang with bandleader Herbie Fields and Jerry Wald's big band. She reached her greatest acclaim in the mid-1950s, recording several solo albums for both Bethlehem Records and Atlantic Records.

After a period of semiretirement, Connor made a comeback in the mid-70s, making albums with Kenton and Maynard Ferguson and making several successful concert tours.

Connor's last public show came in 2004, when she performed on a New York club stage with noted jazz vocalist Anita O'Day.
