Conversation so far:
when was the k foundation started?
The K Foundation was an arts foundation established by Drummond and Cauty in 1993 following their 'retirement' from the music industry.
did they really retire or was it for a short period?
From 1993 to 1995 they engaged in a number of art projects and media campaigns, including the high-profile K Foundation art award (for the "worst artist of the year").
where there any other post retirement projects?
Most notoriously, they burnt what was left of their KLF earnings--a million pounds in cash--and filmed the performance.
why did they burn it?
CANNOTANSWER.

Question: any interesting information?
Self-contained rewrite: other than their post-retirement projects, is there any interesting information about Drummond and Cauty?
