Hendrix would be an unusual and interesting choice. He faced *a lot* of racism. He was expelled from school for holding hands with a white girl. He grew up in Washington state where racism wasn't as prevalent as in the deep south, but he still had issues when he toured. He was called "the Wild man of Borneo," a racist slur in its own way. After he became famous, people either treated him as superman, less than a man, but rarely as just a man.
He made a significant contribution to the way rock music was played. People played mostly "clean" before Hendrix tore things up with distortion pedals--he even invented the wah wah. He died when he was only 27. Imagine what he could have done if he had lived longer.
Hendrix was half black and half Native American, by the way, but I wouldn't think that would matter here.
