by Stephen Thomas ErlewineBo Diddley's major-label '90s comeback effort A Man Amongst Men is overflowing with guest stars, but it rarely gels into something distinctive. The presence of such heavyweights as Keith Richards, Ron Wood, and Jimmie Vaughan actually weighs down the set, preventing Diddley from digging deep into the grooves. The band never quite rocks hard enough and no one tears off an inspired solo -- A Man Amongst Men is pleasant, but it never approaches compelling listening.
