In the 1970s and '80s, Richey ran Warehouse Music, a mail order company that offered a full range of musical instruments and equipment, acting in many cases as a distributor for factory-licensed dealers in Fender, Gibson, and other brands, and selling them at a generous discount.
In 1977 Slim Richey recorded "Jazz Grass", an album of mostly bluegrass musicians forsaking their mountain roots to play more harmonically-sophisticated jazz.
