Kelley Gant's website used to read, "Unfortunately, Kelley is not yet a mainstay in the Kansas City jazz scene." Fortunately, that has been updated. Mentored by Everette DeVan, Gant had co-hosted, with Dionne Jeroue, DeVan's Tuesday-night jams at the Phoenix. Now Gant is breaking out with her own group, including expert bassist Bob Bowman and guitarist Rod Fleeman. Twenty years ago, Bowman and Fleeman were backing singer Karrin Allyson in Kansas City and on Grammy-nominated albums. They know how to support a female vocalist who is becoming — as anyone who hears Gant will understand — a jazz-scene mainstay.
