CRANBERRY TWP - By day, Donna Bailey is an employee of a health care company, but by night, she's got "Fever."

It's catchy. It lingers. And no one's in a hurry to find a cure.

Township resident Bailey, 51, sings jazz, hot and shivery cool, depending on the tune.

"She's got a magnetic stage presence and has learned the attitudes that contribute to the making of a successful singer," said Paul Negy, a spokesman for the Pittsburgh Jazz Society for whom Bailey has sung. "She's got great rapport with the audience and she makes you like her. With her, what you see is what you get ... and that's class and style."

"We had her here in March and our crowd was mesmerized," said Pat Erdelsky of the Westmoreland Jazz Society. "She's a powerful performer, and we'll make sure she comes back."

While Bailey has sung all her life, in the past 10 years she has found the "niche that's comfortable for me," favoring American standard jazz sung by her own personal favorites such as Frank Sinatra, Tony Bennett, Ella Fitzgerald and Sarah Vaughn.

"I love these old tunes and being able to interpret them," she said.

She took a break in her career to raise her children, just performing locally and for private occasions. Now with her youngest in high school, she's revved up her performing and recording schedule.

"I'm busier than ever and I appreciate my audience," said Bailey.

She sings most of the time with a combo of Jason Holler on bass; Mason Embry, piano; Lou Stellute, saxophone; and Gordon Grottenthaler on drums. Often, Alex Lang adds his saxophone to the group.

"We do clubs and have such a good time. When we tour, we get to play with everybody. I get to play with the best jazz musicians," she said.

According to Negy, Martini's Restaurant, behind the Century III Mall, Route 885S in Monroeville, is a hot place for jazz, right up there with Dowe's on Ninth in downtown Pittsburgh, which attracts national and international jazz stars.Bailey's sung at both places as well as taking the mike at the Penn Brewery and the James Street Tavern, both on Pittsburgh's North Side.As a member and singer for both the Pittsburgh and Westmoreland Jazz societies, Bailey has had the chance to interact with many musicians of national renown. She had the opportunity to sing with jazz guitarist Ron Anthony and was asked to record a jazz piece written by Sammy Kahn. "It's Always 4 a.m." is on her new CD titled "Becoming...Ballads, Bossas and Beyond," available in May. The CD will be available on her Web site, donnabaileyjazz.com, amazon.com or at her concerts in the Pittsburgh area.A native of West Virginia, Bailey has made her home in Cranberry for 10 years.
