Found dance music very electronic and revolutionary (10)
I believe the answer is:
discovered
'found' is the definition.
('discover' can be a synonym of 'find')
'dance music very electronic and revolutionary' is the wordplay.
'dance music' becomes 'disco' (type of dance music).
'very' becomes 'v' (abbreviation).
'electronic' becomes 'e' (as in e-mail or e-books).
'and' is a charade indicator (letters next to each other).
'revolutionary' becomes 'red' (red can informally mean communist).
'disco'+'v'+'e'+'red'='DISCOVERED'
(Other definitions for discovered that I've seen before include "Unexpectedly found" , "Found during search" , "Was the first to observe" .)
