Composer protested after changing direction ultimately (5)

I believe the answer is:

satie

I'm a little stuck... Click here to teach me more about this clue!

'composer' is the definition.
(French composer Erik Satie)

I don't understand how the rest of the clue works.

(Other definitions for satie that I've seen before include "French avant-garde composer, Erik, d. 1925" , "posed by yours truly close to stage" , "French composer (Trois Gymnopedies)" , "Erik -, nineteenth to twentieth century French composer" , "scorer" .)

I've seen this clue in The Guardian.
