Art Forms of Dimensions Tomorrow is an album by the American jazz musician Sun Ra and his Solar Arkestra.

Often considered the first of Ra's 'outside' recordings,[4] the album was the first to make extensive use of a discovery by the Arkestra's drummer and engineer Tommy Hunter: 'Art Forms of Dimensions Tomorrow.... contained "Cluster of Galaxies" and "Solar Drums", two rhythm section exercises with the sound treated with such strange reverberations that they threatened to obliterate the instruments' identity and turn the music into low-budget musique concrète.

By working the volume of the output on the playback I could control the effect, make it fast or slow, drop it out, or whatever."

When re-issued on compact disc by Evidence in 1992, the album was joined with the contemporaneous Cosmic Tones for Mental Therapy.

All songs by Sun Ra Side A: Side B: [1] Recorded entirely at the Choreographer's Workshop, New York (the Arkestra's rehearsal space) in 1962, except "Lights on a Satellite" and "Kosmos in Blue", recorded in the same location in either November or December 1961.
