Album of new arrangement for strings? (9)

I believe the answer is:

recording

'album' is the definition.

I cannot understand how the rest of the clue works.

(Other definitions for recording that I've seen before include "Taping" , "Transcription" , "Eg, something on CD" , "Writing down or registering electronically" , "Tape" .)

I've seen this clue in The Independent.
