Singers almost contrived mike drops? (5)
I believe the answer is:
altos
'singers' is the definition.
(alto is a kind of singer)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for altos that I've seen before include "Highest male, lowest female, voices" , "High male or low female voices" , "Females who sing in the lowest range" , "Choir members" , "Singers" .)
