When it comes to rock and roll bloodlines, you'd be hard pressed to find an active artist with a more impressive pedigree than bassist/vocalist Glenn Hughes, who fronts British/American supergroup Black Country Communion. Hughes, who was born in 1951 in Staffordshire, England, came to prominence in the early '70s as a member of British funk-rock pioneers Trapeze. That led to a career-making spot in the Mk. III and IV lineups of Deep Purple in the mid-'70s, when he replaced Roger Glover and evolved into one of the band's main songwriters, co-penning "Holy Man," "You Keep On Moving" and "The Gypsy."
