I didn’t either when I first heard her. Then, about 25 yrs ago I ran across a collection of CDs of Atlantic recordings from the 1950’s- 1980’s, digitally remastered, of a number (there were many) of their R&B artists. Terrific stuff, including Aretha.
Great sonics can improve one’s appreciation of music.
Before anyone writes off Aretha Franklin, they should be forced to listen to the live recording of her at the Fillmore West backed by King Curtis’ band with Billy Preston and the Memphis Horns.
... and if they still don’t dig it, then they just don’t have any soul!
