Artist's debut release for family member (6)
I believe the answer is:
auntie
'for family member' is the definition.
(I've seen this before)
'artist's debut release' is the wordplay.
'debut' indicates taking the first letters.
'release' becomes 'untie' (eg to untie restraints).
The initial letter of 'artists' is 'a'.
'a'+'untie'='AUNTIE'
(Other definitions for auntie that I've seen before include "Untie a relative" , "Unite a strange relative" , "BBC; relative (colloq,)" , "Name for BBC" , "Unite a strange family member" .)
