Rock and R&B embraced by fellow (6)
I believe the answer is:
marble
'rock' is the definition.
(I know that marble is a type of rock)
'rb embraced by fellow' is the wordplay.
'embraced by' indicates putting letters inside.
'fellow' becomes 'male' (fellow can mean a man).
'rb' placed within 'male' is 'MARBLE'.
'and' is the link.
(Other definitions for marble that I've seen before include "Rock used for sculptures" , "'Hard, crystalline rock (6)'" , "Fine stone" , "Hard shiny stone used by sculptors" , "Hard crystalline limestone used for sculpture" .)
