Thrash metal about right for this band (6)
I believe the answer is:
armlet
'this band' is the definition.
(armlet is a kind of band)
'thrash metal about right' is the wordplay.
'thrash' indicates anagramming the letters (I've seen this in other clues).
'about' indicates putting letters inside.
'right' becomes 'r' (abbreviation).
'metal' is an anagram of 'amlet'.
'amlet' placed around 'r' is 'ARMLET'.
'for' acts as a link.
(Other definitions for armlet that I've seen before include "Band on limb" , "Band worn for decoration" , "Type of bracelet" , "Member may be surrounded by this" , "Band round sleeve" .)
