You may look for his live albums as well,I am aware of 3 of them,and also he recorded lots of albums as a guest guitarist in that period which are worth of listening,usually with some organ player,like big john patton,or baby face willete,or with pianist like sonny clark.He died in 1979,and maybe only some recordings in 70's are not so interesting because he was trying to make some money and therefore his recordings were made for commercial reasons more than artistic,but mayority of his work in almost 15 yeras are highly recommened.Try Kenny Burell,or Wes Mongomery as well
