The more I learn about Mark Kelley, the new bass player for The Roots the more I like. His groove is nasty and his tone when playing with other artist on the Jimmy Fallon show has me walking through life this week half there. Half there cause my brain is thinking about how sick his tone was. He is a different player than their last two bassist Owen Biddle and Leonard Hubbard, but he fits in so well. I look forward to learning more about him and hearing his playing every night on the Jimmy Fallon Show.
