The range of some folksier rapper (6)
I believe the answer is:
sierra
'the range of' is the definition.
(I've seen this before)
'some folksier rapper' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'SIERRA' is hidden within 'folksier rapper'.
(Other definitions for sierra that I've seen before include "Mountain range in Spanish-speaking countries" , "Range of mountains with jagged peaks" , "Long range" , "A Spanish mountain chain (6)" , "- - Leone" .)
