Otis Rush (born April 29, 1935 in Philadelphia, Mississippi) is maybe the greatest guitar king ever to make chicago blues. He is also well known for his electrifying voice and for being one of the first baritones to reach popularity in the blues industry. Rush uses his great voice to deliver his songs with plenty of experience and pure emotion. Otis Rush was born in 1935 as one of seven children. Rush worked in the fields to help his mother in his younger days. Otis, along with his other brothers and sisters, had to support each other without the help from a father figure.
