I had just finished listening to one of my favorite CDs and thought I would listen to the radio for a while. The first Song I heard on the radio was from a band that had the same lead singer as the CD I just finished listening to. I thought it would be neat to intermix the two band names and it provided an interesting nickname.

Spoiler:
'A Perfect Circle' > APC
Tool + APC ~ A + to + P + ol + C = Atopolc
