Song from upcoming prog band receiving a negative response (3,6)
I believe the answer is:
sea shanty
'song' is the definition.
(song sung at sea)
'upcoming prog band receiving a negative response' is the wordplay.
'upcoming' is a reversal indicator.
'prog band' becomes 'Yes' (Yes are a progressive rock band).
'receiving' indicates putting letters inside.
'negative response' becomes 'shan't' ('I shan't!').
'yes' written backwards gives 'sey'.
'a'+'shant'='ashant'
'sey' enclosing 'ashant' is 'SEA SHANTY'.
'from' acts as a link.
(Other definitions for sea shanty that I've seen before include "Traditional song sung by sailors" , "A certain air" .)
