Mother's Finest are notable partly because they are an "interracial" rock group from the US South. Their music was a blend of funky rhythm, heavy guitars and expressive rock singing. Their album Mother's Finest from 1976 today is a rare collector's piece and contained with the ironic song "Niggizz Can't Sing Rock'n Roll" (although they were criticized for it by an important religious leader and dropped it from their live concerts). In the summer of 1977, they opened for The Who in their laser lit tour through Canada. An unusual choice of opening acts, they impressed with their performance and choreographed stage show. In 1978 they were guests in German broadcast Rockpalast and with one concert they gathered a cult status in Europe which lasts until today (this concert appears on the DVD Mother's Finest - At Rockpalast).
Mother's Finest was well respected within the southern rock musical community. Their fellow Epic Records label-mates The Stranger would play "Another Mother Further" as their introductory music. (via wikipedia)
