In the large stable of blues talent that Crowley, LA, producer Jay Miller recorded for the Nashville-based Excello label, no one enjoyed more mainstream success than Slim Harpo. Just a shade behind Lightnin Slim in local popularity, Harpo played both guitar and neck-rack harmonica in a more down-home approximation of Jimmy Reed, with a few discernible, and distinctive, differences. Harpos music was certainly more laid-back than Reeds, if such a notion was possible. But the rhythm was insistent and, overall, Harpo was more adaptable than Reed or most other bluesmen. His material not only made the national charts, but also proved to be quite adaptable for white artists on both sides of the Atlantic, including the Rolling Stones, Yardbirds, Kinks, Dave Edmunds with Love Sculpture, Van Morrison with Them, Sun rockabilly singer Warren Smith, Hank Williams, Jr., and the Fabulous Thunderbirds.

A people-pleasing club entertainer, he certainly wasnt above working rock & roll rhythms into his music, along with hard-stressed, country & western vocal inflections. Several of his best tunes were co-written with his wife Lovelle and show a fine hand for song construction, appearing to have arrived at the studio pretty well formed. His harmonica playing was driving and straightforward, full of surprising melody, while his vocals were perhaps best described by writer Peter Guralnick as if a black country & western singer or a white rhythm & blues singer were attempting to impersonate a member of the opposite genre. And here perhaps was Harpos true genius, and what has allowed his music to have a wider currency. By the time his first single became a Southern jukebox favorite, his songs were being adapted and played by white musicians left and right. Here was good-time Saturday-night blues that could be sung by elements of the Caucasian persuasion with a straight face. Nothing resembling the emotional investment of a Howlin Wolf or a Muddy Waters was required; it all came natural and easy, and its influence has stood the test of time.
