I believe the answer is:

dwell

I'm a little stuck... Click here to teach me more about this clue!

'live' is the definition.
(to live/dwell somewhere)

'band's extreme sound' is the wordplay.
'band's extreme' becomes 'd' (I can't justify this - if you can you should believe this answer much more).
'sound' becomes 'well' (I've seen this before).
'd'+'well'='DWELL'

Can you help me to learn more?

(Other definitions for dwell that I've seen before include "Reside - linger" , "stay" , "Focus attention (on)" , "Live (in a place)" , "Lodge" .)

I've seen this clue in The Independent.
