Cobain's band in blissful state (7)
I believe the answer is:
nirvana
'blissful state' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nirvana that I've seen before include "religious state" , "Eastern place of complete bliss" , "Eastern place or state of bliss" , "Buddhist 23" , "Buddhist state of perfect bliss" .)
