Trippy stoner music? (4,4)
I believe the answer is:
acid rock
'trippy' is the definition.
I can't tell whether this defines the answer.
'stoner music?' is the wordplay.
'stoner' becomes 'acid' (I can't explain this - if you can you should believe this answer much more).
'music?' becomes 'rock' (rock is a kind of music).
'acid'+'rock'='ACID ROCK'
Can you help me to learn more?
(Other definitions for acid rock that I've seen before include "Supposedly drug-inspired musical style" , "Style of popular music" .)
