In the 1970s, Diamond expanded its catalog to include pop and country music, signing artists like Johnny Lee and Tanya Tucker. The label's ability to adapt to changing musical trends helped it maintain relevance through the decades. Although Diamond Records eventually declined in the late 1980s, its legacy endures through its contributions to the development of rhythm and blues and rock music.
