Alto records wide range (4)
I believe the answer is:
alps
'range' is the definition.
(mountain range)
'alto records wide' is the wordplay.
'alto' becomes 'a' (musical abbreviation).
'records wide' becomes 'lps' (LP is a type of record. I am not sure about the 'wide' bit.).
'a'+'lps'='ALPS'
Can you help me to learn more?
(Other definitions for alps that I've seen before include "European mountain chain" , "Peaks" , "Slap about in mountains" , "Slap (anag.)" , "Mont Blanc mountains" .)
