John O'Brien made a comment on Suresh's blog-review of Couples Retreat. There was some interesting info about the music :
"Hi Guys, John O'Brien here. A nice rounded conversation about the score. AR was left to his own creativity on this film. There were a few spotting sessions with myself, the director Peter Billingsley, the editor Dan Lebenthal and the Music Editor Jim Weidman. I would say the most input came from Jim Weidman and Peter Billingsley. We scored in Los Angeles at the Sony soundstage. AR did most of the composing in Mumbai and a little in Hollywood. AR was a dream to work with and yes his "Shark" cue was very inventive, knowing he could have gone a "safe" route. My main job description as music supervisor is to find "needle drops' or original songs to place into the film at key scenes such as the Eden East nightclub. I have scored and done music supervision on other films. I composed six original cues for this film. Peter asked me to do the Lua cue and it was very generous of AR to have it included on the soundtrack. Keep up the conversation, I'm enjoying it very much." http://backgroundscore.blogspot.com/2009/09/listening-couples-retreat.html
