My brother and I were in a record store looking through the bargain bin, and there was a copy of Cream’s Disraeli Gears, and right next to it, Muddy Waters’ Hard Again,” Todd Cambio says. “At the time, I was 14 and trying to play harmonica. I really wanted to buy Disraeli Gears, but my brother told me to get Hard Again because Muddy always had the best harmonica players.

I thought he was trying to talk me into it because he didn’t have any money, but I reluctantly bought it. When we got home, I put it on, thinking I’d get it out of the way. I knew I was never going to listen to it again.” He was in for a shock. “The first song was ‘Mannish Boy,’ and the hair raised on my head. I was bitten. After that, that was all I listened to.”
