Pride and Joy showcases Stevie Ray Vaughan's ability to drive a shuffle groove while simultaneously playing lead lines — a technique rooted in the Texas blues tradition of T-Bone Walker. Vaughan plays rhythm and lead guitar simultaneously throughout, and the solo's mixture of double stops, stinging single notes, and whammy bar expression demonstrates why he is regarded as the greatest blues guitarist of his generation.
