Diane Hubka: Haven’t We Met?

East-Coast vocalist Diane Hubka possesses an unadorned singing style that is perfect for ballads such as “Lazy Afternoon” and “Alone Together.” But when it’s time to accelerate the tempo, she’s totally able and adept. An excellent improviser, she capably handles the angularly complex lines of “Israel,” enriched by the searing alto sax of Lee Konitz, who also guests on Jobim’s “Favela” and “Detour Ahead.” The core quartet of pianist Frank Kimbrough, guitarist John Hart, bassist Harvie Swartz and drummer Ron Vincent are superb throughout, particularly on Kenny Rankin’s title track.
