Donald â€œDuckâ€ Dunn, the bass guitarist whose bouncy rhythms helped define the Memphis soul sound of Stax Records and graced recordings by Otis Redding, Wilson Pickett, the Blues Brothers, Booker T. and the MGs, Eric Clapton and Rod Stewart, died May 13 in Tokyo. He was 70. His longtime collaborator, guitarist Steve Cropper, announced Mr. Dunnâ€™s death online but did not specify a cause. Mr. Dunn and Cropper had been performing at a Tokyo nightclub in a revue of Stax performers. Mr. Dunn played on such classic soul hits as Pickettâ€™s â€œIn the Midnight Hourâ€ (1965), Eddie Floydâ€™s â€œKnock on Woodâ€ (1966), Sam and Daveâ€™s â€œSoul Manâ€ (1967) and Reddingâ€™s â€œSittinâ€™ On the Dock of the Bayâ€ (1968) â€” all from the Stax studio where Mr. Dunn was in the house band, Booker T. and the MGs. Stax, with its bluesy, gritty sound and spontaneous approach to recording, rivaled Motown in popularity among soul fans. Booker T. and the MGs (or MGâ€™s as they were later billed) â€” Mr. Dunn, Cropper, drummer Al Jackson Jr. and organist Booker T. Jones â€” also crafted such memorable instrumentals as â€œTime is Tightâ€ (1969) and the Latin-flavored â€œSoul Limboâ€ (1968). The name MGs reportedly stood for â€œMemphis Group.â€ Jones had earlier played in a band named the Triumphs â€” a fact that helped lead many people to believe that the band was named after the English sports car, the MG.
