'band' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'son speaks highly of full of dicks' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'speaks highly of' becomes 'extols' (I've seen this in another clue).
'full of' is an insertion indicator.
'dicks' becomes 'pis' (I've seen this in another clue).
'extols' going around 'pis' is 'expistols'.
's'+'expistols'='SEX PISTOLS'

(Another definition for sex pistols that I've seen is " Punk rock group".)
