Sister Rosetta Tharpe is often referred to as "the godmother of rock and roll" for her pioneering guitar technique, use of distortion/reverb, and a 1963 UK tour with Muddy Waters that has been cited as a huge influence by Eric Clapton, Keith Richards, and Jeff Beck. Though she reached more widespread notoriety across the world in the '50s and '60s thanks to the folk/blues revival and her beloved status among UK blues and rock musicians, it's her early recordings from the late '30s and early-mid '40s that are the most brilliant, visceral, and emotional of her career. This excellent collection compiles 18 of those amazing gospel and R&B sides into one place. Essential.
