Composer, I understand, residing in Long Island (6)

Ross

I believe the answer is:

ligeti

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

'i understand residing in long island' is the wordplay.
'understand' becomes 'get' (getting is a kind of understanding).
'residing in' means one lot of letters goes inside another.
'long' becomes 'l'.
'island' becomes 'i'.
'i'+'get'='iget'
'l'+'i'='li'
'iget' put inside 'li' is 'LIGETI'.

(Another definition for ligeti that I've seen is " Composer whose work Lux Aeterna featured in 2001: A Space Odyssey".)

I've seen this clue in The Independent.
