As the label grew and, business expanded Rainbow Sound Inc added a studio and recording equipment. In 1969 Massegee brought in Bob Cline as a full time engineer and manager at Rainbow Sound Inc. The labels continued to grow. Between 1969 to 1971 alone Rainbow Sound recorded over 200 Gospel albums! Rainbow Sound Inc became one of the first to make sound-tracts for Gospel singers to record with. At the height of Rainbow Sound Inc. the label had over 4000 singers involved in their sound tract club. Rainbow Sound Inc. was sold in 1982 and under new ownership the label failed quickly.
