No vocal gymnastics at this hot rock venue (7)
I believe the answer is:
volcano
'rock venue' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'no vocal gymnastics at this hot' is the wordplay.
'no vocal' anagrams to 'VOLCANO'.
However, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for volcano that I've seen before include "Lava-spewing mountain" , "Mountain (could be a heavy smoker!)" , "Etna, for example" , "Dormant or active mountain" , "A fissure in the earth's crust with molten rock" .)
