The KLF - the greatest band ever?

I'm late to this party (mostly because their music had been unavailable for so long) but I've been discovering The KLF (Kopyright Liberation Front) also known as the JAMs (Justified Ancients of Mu Mu), The Timelords, etc. the past couple weeks, and everything I check out (music, videos, films, etc.) has been nothing short of mind blowing.

Anyone else just becoming familiar with them? Any longtime fans?
