Music from one of the Stones? (4)
I believe the answer is:
rock
'music' is the definition.
(rock music)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for rock that I've seen before include "musical genre?" , "Hard stone or lively music" , "lull baby to sleep?" , "Large stone - type of music" , "solid?" .)
