Gibson named Ben one of the Top 10 Modern Blues Guitarists. Here's what they had to say about him:
"Just like with Derek Trucks, Ben Harper's style of music span many different genres, with blues being one of the underlying inspirations. Although he's a multi-instrumentalist, Harper's signature instrument is playing acoustic slide guitar. Just listen to songs like “Homeless Child,” “Whipping Boy,” and “I Want To Be Ready” for a taste of how Harper incorporates the blues in his music."
