Extremely suggestive text sent to musicians (6)
I believe the answer is:
sextet
'to musicians' is the definition.
(a sextet is a group of six musicians)
'extremely suggestive text sent' is the wordplay.
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'sent' indicates anagramming the letters (send can mean to excite or stimulate).
'suggestive' with its centre removed is 'se'.
'text' is an anagram of 'xtet'.
'se'+'xtet'='SEXTET'
(Other definitions for sextet that I've seen before include "Group of six performers" , "Musical work" , "Music for six" , "Group of six (X, not S)" , "composition" .)
