The connection between toxicity and cancer and safe air and water and food, all of that was important all along, as were women's and human rights issues, but the nuke issue and the safe energy movement became really important to me in the mid-'70s.

One of the biggest obstacles I've overcome in my life was thinking I didn't deserve to be successful. Artistically I'm not as much of a heavyweight as someone like Paul Simon or Joni Mitchell, because I'm not a creator of original music, and I worried about that for years.

I'm sure I would have been considered a more significant artist if I was a singer-songwriter. It's just not the way I roll. I love being a curator and a musicologist. People write me letters and thank me for turning them on to Fred McDowell and Sippie Wallace, and that's partly my job this time around.

One of the things that I'm glad about, though, is that regular people can relate to me.

I'm certain that it was an incredible gift for me to not only be friends with some of the greatest blues people who've ever lived, but to learn how they played, how they sang, how they lived their lives, ran their marriages, and talked to their kids.

I was raised with the blessing of being involved with peace and social justice, and the environmental movement. I have my parents to thank for that.

I finally learned to accept that I can't make radio play blues any more than I could get Reagan out of the White House.
