Art Forms of Dimensions Tomorrow, a key transitional album in the Sun Ra catalog, was produced in two sessions shortly after the bandleader's 1961 migration from Chicago to New York (with a brief stopover in Montreal). One of about a dozen Arkestra albums recorded at the Choreographer's Workshop, Art Forms displays Sun Ra's increasing tendency to juxtapose stylistic incongruities on vinyl in the interests of showcasing his versatility—or accommodating restless attention spans (perhaps his own).
