The music of Otis Spann is immediate and urgent, completely clear in its content. Otis is one of the great and thoroughly authentic blues storytellers. Into his blues piano playing Otis put his soul. As part of the Muddy Waters' band he could frequently be found in Chicago's south side performing nightly with Muddy, who treated Spann as his protégé and referred to him as his half brother. And under Waters guidance, Otis Spann emerged as a top-notched musician, and took command of his own sessions as well.
