Aretha Franklin had spent years at Columbia Records with moderate success before moving to Atlantic Records in 1967. It was there, recording at FAME Studios in Muscle Shoals, Alabama, that she truly found her sound. Her cover of Otis Redding's 'Respect' became a definitive anthem for the civil rights and feminist movements. Franklin didn't just sing the song; she rearranged it, adding the iconic 'R-E-S-P-E-C-T' spelling and the 'sock it to me' refrain. Her powerful, gospel-trained voice and piano playing became the gold standard for soul music. She was the first woman inducted into the Rock and Roll Hall of Fame in 1987 and won 18 Grammy Awards during her career. Her performance at the inauguration of Barack Obama in 2009 remains one of the most memorable live vocal performances in American history.
