Conversation so far:
What was going on with the group?
After a four-year hiatus, rumours of mental illness began to spread which turned out to be nothing more than exaggeration of Cobain's mercury poisoning from fillings in his teeth.
When did they make more music?
The pair returned in 2002 with "The Isness".

Question: How did the music sound?
Self-contained rewrite: How did the music from Future Sound of London sound?
