I remember when this album came out and Sparks were really big. They've had a couple of hits and a trilogy of albums. Kimono my house was the first and Indiscreet was the last. This album is firmly placed in the middle and was always the difficult one, the one that made my friends turn away from Sparks alltogether. I, however was more persistant, and was able to find the jewel inside. Granted, it takes a great many listens to fully get your grip on, mainly because of the mad tempo they keep throwing their ideas and twists onto you the listener, but here they are at their musical and lyrical peak. There used to be eleven tracks on this album, now there are thirteen. They are all hits.
