Reviews Indian music a couple of times, as it's a cultural phenomenon at The Strand
I believe the answer is:
agar-agar
'times as it's a cultural phenomenon at the strand' is the definition.
I can't judge whether this definition defines the answer.
'reviews indian music a couple' is the wordplay.
'reviews' says the letters should be written in reverse (view the letters another way).
'indian music' becomes 'raga' (I've seen this before).
'a couple' says to double the letters.
'raga' backwards is 'agar'.
'agar' duplicated is 'AGAR-AGAR'.
'of' is the link.
Can you help me to learn more?
(Other definitions for agar-agar that I've seen before include "Gelatinous thickening for food" , "Food thickener from seaweed" , "Thickener obtained from seaweed" , "Jelly from seaweed" .)
