Confused impression of Britpop band (4)
I believe the answer is:
blur
This clue is a double definition.
'confused impression' is the first definition.
(I've seen this before)
'britpop band' is the second definition.
(band in Britpop genre)
'of' is the link.
(Other definitions for blur that I've seen before include "This Brit-pop band is a bit hazy" , "Indistinct mark" , "Mist" , "Unfocused image" , "Out-of-focus image" .)
