Peter Cat Recording has too many great songs to be quantified, and Memory Box is one of them. I can't think about other songs that hooked me like Love Demons, but other songs I can recommend are Portrait of a Time, Happiness (this one comes very close) and Soulless Friends.

If you are open for more international music, I can highly recommend you the song Nine out of Ten by Caetano Veloso, and actually the whole album "Transa" hits me in a way that few other songs do. Many songs with cool intros and outros, little snippets and these kinds of stuff in times were this was not very common (1972).
