"In the overpopulated field of jazz singers which includes quite a few strong talents, Rebecca Hardiman stands out from the crowd. She has a beautiful voice, not only sings perfectly in tune, but caresses the center of each note and swings up a storm. Rebecca deserves to be much better known beyond the Pacific Northwest..she's one of the current greats." ~ Scott Yanow, Jazz Journalist/Historian - LA Jazz Times
