Whether fusing a contemporary lilt and old standards or rousing an audience with jazz-infused twists of pop, Dionne Jeroue has a voice that soars. She's one of two jazz singers emerging at Everette DeVan's Tuesday-night jams at the Phoenix. (DeVan is the master swinging a Hammond B3 organ.) But a jam session limits exposure. The solution: an entire evening of Jeroue with Everette's trio (adding Matt Hopper on guitar and Danny Rojas on drums). This Thursday, they're swinging and rousing the Green Lady Lounge, where stepping inside feels like time traveling 70 years into KC's jazz past.
