Vigorous piece from Stravinsky (4)

I believe the answer is:

igor

'stravinsky' is the definition.
(I've seen this before)

'vigorous piece from' is the wordplay.
'from' indicates a hidden word.
'IGOR' can be found hidden inside 'vigorous piece'.

(Other definitions for igor that I've seen before include "Russian man" , "Maybe 8 [SIKORSKY]" , "Card game" , "-- Stravinsky, composer" , "Stravinsky's first name" .)

I've seen this clue in the Evening Standard.
