Sam Moore and Dave Prater had been a hot commodity in the world of rhythm and blues since Hold On, I'm Comin', their 1966 debut album on Stax Records, which they took to the top of the Billboard R&B Charts, but it was their third studio effort, 1967's Soul Men, that served as their full-fledged mainstream breakthrough, hitting No. 2 on the Billboard Top 200. Soul Men is a virtual blueprint for countless other '60s acts but none could quite reproduce the dynamic duo's sheer raw soul power as heard on timeless titles like "Soul Man," "May I Baby," "Hold It Baby," "I'm With You" and "Rich Kind Of Poverty."
