A native of Pittsburgh, Pennsylvania, Dale "DrBlooz" Duffala's early musical training was on keyboards and trombone. Duffala played with several jazz and soul bands before moving to Chicago by way of Philadelphia and Kansas City. He has occasionally sat in with such Chicago players as Lonnie Brooks, Gloria Hardiman, Rockin' Johnny, and Gloria Thompson.
Originally a classically trained pianist, his blues influences include Willie Dixon and Tommy Shannon on bass, and Muddy Waters and Johnny Winter in general. "Tommy Shannon was the first person to put a bass on me, and his versatility gives me great inspiration. And, of course, Willie wrote so many great songs, and is the standard for traditional blues bass players." He is a fan of both traditional and contemporary blues players, spanning such artists as Robert Cray, Koko Taylor, BB King, and Shemekia Copeland.
