A Notion in Perpetual Motion is a live album by European jazz group the Vienna Art Orchestra recorded in Switzerland which was first released in 1985 on the Hat ART label as a double LP as Perpetuum Mobile then re-released in 1992 as a single CD.

[1][2] The Allmusic review stated: "the most notable thing about the Vienna Art Orchestra is its stage presence: Rüegg knows how to create drama and surprise and his musicians are more than up to the challenge, clearly delighting themselves in the process.

A Notion in Perpetual Motion is as close to a "perfect" live recording of the VAO as you are likely to find".
