Somewhat lamentable, austere scene (7)
I believe the answer is:
tableau
'scene' is the definition.
(thesaurus)
'somewhat lamentable austere' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'TABLEAU' is hidden within 'lamentable austere'.
(Other definitions for tableau that I've seen before include "Dramatic scene (where the action is frozen?)" , "still life?" , "Depiction of a scene by people in costume" , "Group of people arranged as for a painting say" , "Scene represented by motionless figures" .)
