Artists backed by a musical group for dance (8)
I believe the answer is:
saraband
'dance' is the definition.
(saraband is a kind of dance)
'artists backed by a musical group' is the wordplay.
'artists' becomes 'ras' (Royal Academicians abbreviation).
'backed' says the letters should be written backwards.
'by' is a charade indicator (letters next to each other).
'musical group' becomes 'band' (band is a kind of musical group).
'ras' backwards is 'sar'.
'sar'+'a'+'band'='SARABAND'
'for' is the link.
(Other definitions for saraband that I've seen before include "Old, courtly dance" , "dance music" , "Stately dance" , "Slow Spanish dance" .)
