Groups of instrumentalists discordant endless beat, lacking ecstasy (5,5)
I believe the answer is:
steel bands
'groups of instrumentalists' is the definition.
The answer and definition can be both groups as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'discordant endless beat lacking ecstasy' is the wordplay.
'discordant' indicates an anagram.
'lacking' suggests deleting specific letters.
'ecstasy' becomes 'E' (informal term for the drug).
'endless'+'beat'='endlessbeat'
'endlessbeat' with 'e' taken out is 'ndlessbeat'.
'ndlessbeat' with letters rearranged gives 'STEEL BANDS'.
Can you help me to learn more?
(Other definitions for steel bands that I've seen before include "Say half-inch ribbons" , "West Indian groups" , "features of carnival?" .)
