Tommy Castro

At the 2010 Blues Music Awards in May, Tommy Castro and his bandmates walked away with four awards: band of the year, contemporary blues male artist, contemporary blues album (for Hard Believer), and the big one -- B.B. King Entertainer of the Year.

In a recent phone interview, Castro sounded genuinely grateful and surprised. "You need a shot in the arm," he said. "It was a big night for us." And with a charming lack of vanity, Castro offered two explanations for his four-for-four night specifically, and for his success generally.

"I got opportunities to have a career playing blues, I think, before I was really ready for it," he said. "When Blind Pig signed me [in the mid-1990s], I didn't have any songs. ... I've been learning how to do this while I was doing it. ... I think that over a period of time we've gotten a little bit better at making records."

He credited having a good band, a good producer, and good songwriter partners. "My talent might lie in surrounding myself with all the right people to help me do what I do best," he said. "I have my little thing that I do. I'm a fairly proficient songwriter, I'm a good singer, and a good guitar player. I don't think I'm great at any of those things. ... I'll take all the help I can get."

Ana Popović

It might seem strange for a European to be born into the blues, but that was the case for Ana Popović.

"This is the only thing that I remember as far as music growing up in Serbia," said the Belgrade-born singer, songwriter, and guitarist in a recent phone interview. "We never listened to Serbian music, and basically none of the European stuff ... ."

The blues came both from albums -- "I learned a lot of English from the records," she said, and "I sang those songs way before I could imagine and understand what they were talking about" -- and home jam sessions led by her father. (She eventually wormed her way into those sessions because she learned slide guitar.)

Her first concert (at age 13) was Tina Turner, and one can hear the vocal influence in the fiery defiance and soul of "Wrong Woman," from her 2009 album Blind for Love. Pair that with the subdued, quiet confidence of the same record's "More Real," and it's evident that this is an artist capable of nearly boundless blues. It's overstating her skills, but think Turner paired with Stevie Ray Vaughan and you'll get some sense of this woman's multifaceted attack.

Mud Morganfield

Mud Morganfield has this to say about being the son of Muddy Waters, who also sired (in a less literal way) Chicago blues: "It's a curse, and then sometimes it's a blessing. Because people begin to compare you."

Don't feel too sorry for Morganfield, though. His career is built on re-creating the Muddy Waters sound, and he's almost begging for the comparison.

"I wanted to represent my dad's music, and what he stood for," Morganfield said in a recent phone interview. "It came natural to me. ... People think maybe I was somewhere in the basement studying it, and listening to recordings. You can't get that close with that. I do what I do because I'm his son. That's just all there is to it."
