Obscure Britpop band (4)
I believe the answer is:
blur
'obscure' is the definition.
(both can mean to vague or indistinct)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for blur that I've seen before include "Group - smudge" , "Indistinct mark" , "This Brit-pop band is a bit hazy" , "murky spot" , "fade" .)
