Quick Change World is the fourth solo album released by Ric Ocasek, who was the lead singer and songwriter for The Cars.

Ocasek originally intended for Quick Change World to be a double CD: the "Right Side", consisting of Cars-like pop/rock, and the "Left Side", consisting of experimental music.

When Fireball Zone, Ocasek's third solo release, failed to meet sales expectations, Reprise scaled back the project to this fourteen track single disc, which was issued as Quick Change World in North America only.

The song "Hard Times" was initially intended for the Cars' album Heartbeat City.

It includes the seven "Left Side" tracks that were issued on Quick Change World, and eight tracks that are exclusive to the Negative Theater album.
