Silver included lyrics in more of his compositions at this point, although these were sometimes regarded as doggerel or proselytizing. The first album to contain vocals, "That Healin' Feelin'" (1970), was commercially unsuccessful and Silver had to insist on the support of Blue Note executives to continue releasing music of the same, new style. They agreed to a further two albums that contained vocals and Silver on an RMI electric keyboard; the three were later compiled as "The United States of Mind", but were soon dropped from the catalog.
