Obscure as Albarn's band (4)
I believe the answer is:
blur
'obscure' is the definition.
(both can mean to vague or indistinct)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for blur that I've seen before include "Rock band - make less clear" , "Become unclear" , "Smear, make indistinct" , "Group - smudge" , "Haze - obscure" .)
