Otis Rush's crunching guitar and vocals were never more emphatic than during the '70s when it seemed that he would actually find the pop attention and mass stardom he deserved. These mid-'70s tracks were originally cut for the Black and Blue label, with Rush playing grinding, relentless riffs and creating waves of sonic brilliance through creatively repeated motifs, jagged notes, and sustained lines and licks, while hollering, screaming, moaning, and wailing. Jimmy Dawkins, an outstanding lead artist in his own right, has also long been one of Chicago's great rhythm artists and shows it by adding plenty of tinkling, crackling figures and lines in the backgrounds. While not as consistently riveting as his live Evidence date, this one is also a valuable Rush document.
