Pat Hare

He recorded at the Sun Studio in Memphis, Tennessee, serving as a sideman for Howlin' Wolf, James Cotton, Muddy Waters, Bobby Bland and other artists.

According to Robert Palmer, "Rarely has a grittier, nastier, more ferocious electric guitar sound been captured on record, before or since, and Hare's repeated use of a rapid series of two downward-modulating power chords, the second of which is allowed to hang menacingly in the air, is a kind of hook or structural glue.

According to Allmusic, "what is now easily attainable by 16-year-old kids on modern-day effects pedals just by stomping on a switch, Hare was accomplishing with his fingers and turning the volume knob on his Sears & Roebuck cereal-box-sized amp all the way to the right until the speaker was screaming.

"[1] Hare was reported to have been introverted when sober (once married to Dorothy Mae Good, with whom he had a son and two daughters), but he had a serious problem with alcohol abuse.

The record also features power chords, which remains "most fundamental in modern rock" as "the basic structure for riff-building in heavy metal bands."
