Rolling Stone review initially delighted musician (6,6)

I believe the answer is:

stevie wonder

'musician' is the definition.
(American singer and pianist)

'rolling stone review initially delighted' is the wordplay.
'rolling' is an anagram indicator.
'initially' indicates taking the first letters.
The first letter of 'delighted' is 'd'.
'stone'+'review'+'d'='stonereviewd'
'stonereviewd' anagrammed gives 'STEVIE WONDER'.
