Up until now I never thought I had a favorite. Yet reflecting on Micheal Jackson from his start with the Jackson 5 to his very last works, he by far has had more recordings that I loved than any other artist.
Impossible for me to pick one in any genre let alone overall. Johnny Cash, BB King, Bob Dylan, Ray Charles, Paul Simon, Jimi Hendrix, Jerry Garcia, Stevie Wonder, Bob Marley, James Brown, George Clinton, David Bowie, Michael Jackson, and Prince are all sort of equal pillars at the height of influential solo artistry to me. Then a whole different list of bands.
