by Bill DahlSame band, different producer: this time it was Elvis Presley's legendary guitarist, Scotty Moore, behind the glass as Frost and his pals dished out the lowdown sounds during the mid-'60s for Stan Lewis's Jewel logo. My Back Scratcher owes a stylistic debt to Slim Harpo but feels mighty good all the same. The entire 13-song disc reeks of steamy juke-joint ambience.
