In the mold of Jeff Beck, Carlos Santana, and Mike Bloomfield, Mandel is an extremely creative rock guitarist with heavy blues and jazz influences. And like those guitarists, his vocal abilities are basically nonexistent, though Mandel, unlike some similar musicians, has always known this, and concentrated on recordings that are entirely instrumental, or feature other singers. A minor figure most known for auditioning unsuccessfully for the Rolling Stones, he recorded some intriguing (though erratic) work on his own that anticipated some of the better elements of jazz-rock fusion, showcasing his concise chops, his command of a multitude of tone pedal controls, and an eclecticism that found him working with string orchestras and country steel guitar wizards. Mandel got his first toehold in the fertile Chicago white blues-rock scene of the mid-’60s (which cultivated talents like Paul Butterfield, Mike Bloomfield, and Steve Miller), and made his first recordings as the lead guitarist for harmonica virtuoso Charlie Musselwhite. Enticed to go solo by Blue Cheer producer Abe Kesh, Harvey cut a couple of nearly wholly instrumental albums for Phillips in the late ’60s that were underground FM radio favorites, establishing him as one of the most versatile young American guitar lions. He gained his most recognition, though, not as a solo artist, but as a lead guitarist for Canned Heat in 1969 and 1970, replacing Henry Vestine and appearing with the band at Woodstock. Shortly afterward, he signed up for a stint in John Mayall’s band, just after the British bluesman had relocated to California. Mandel unwisely decided to use a vocalist for his third and least successful Philips album. After his term with Mayall (on USA Union and Back to the Roots) had run its course, he resumed his solo career, and also formed Pure Food & Drug Act with violinist Don “Sugarcane” Harris (from the ’50s R&B duo Don & Dewey), which made several albums. In the mid-’70s, when the Rolling Stones were looking for a replacement for Mick Taylor, Mandel auditioned for a spot in the group; although he lost to Ron Wood, his guitar does appear on two cuts on the Stones’ 1976 album, Black & Blue. Recording intermittently since then as a solo artist and a sessionman, his influence on the contemporary scene is felt via the two-handed fretboard tapping technique that he introduced on his 1973 album Shangrenade, later employed by Eddie Van Halen, Stanley Jordan, and Steve Vai.
