Cue up “Soul Vibrations,” the first track on Verve’s reissue of Dorothy Ashby’s Afro Harping, and revel: a one-note syncopated bass line over a slamming drumbeat that you’re sure you’ve heard sampled somewhere. Enter the double-tracked theremins, followed by swoopy strings. Next, over the relentless beat, an echo-plexed harp solo by Ashby, during which the strings return with 16-notes; then the theremins run the groove into a fade-out. And there you have it: 3’15’’ of pure aural time capsule in all its mod glory.

Born in Detroit in 1932, Dorothy Ashby can be easily recognized as the woman who gave the harp a jazz voice. In her hands, the harp, an originally classical instrument which seemed to just scare people, became a highly versatile swinging voice able to drive a whole jazz rhythm section. Recorded in 1958 by master Rudy Van Gelder and originally released on the Prestige label, Hip Harp is a perfect example of Ashby's artistry. At the head of a fine quartet featuring the great Frank Wess on flute, Herman Wright on bass, and master Art Taylor on drums, Ashby creates a unique combination of deeply jazz elements expressed through a totally new sound.

Issued on Cadet in 1970, The Rubaiyat of Dorothy Ashby is really a left-field offering for the jazz harpist. But being a jazz harpist was – and remains – an outside thing in the tradition. Her previous offerings on Prestige were pure, hard bop jazz with serious session players soloing all over them…
