Several changes occurred in the early 1970s: Silver disbanded his group to spend more time with his wife and to concentrate on composing; he included lyrics in his recordings; and his interest in spiritualism developed. The last two of these were often combined, resulting in commercially unsuccessful releases such as "The United States of Mind" series. Silver left Blue Note after 28 years, founded his own record label, and scaled back his touring in the 1980s, relying in part on royalties from his compositions for income. In 1993, he returned to major record labels, releasing five albums before gradually withdrawing from public view because of health problems.
