The music of A R Rahman

Went to see the London Philharmonic Orchestra at the Royal Festival Hall performing the music of A R Rahman...he of recent Slum Dog Millionaire fame, but of course Rahman has numerous other credits to his name..including his 'first love' - Roja from 1992. Mr Rahman was also at the concert in person for a Q&A session.
LPO were good but I still rate the City of Birmingham Orchestra (CBSO) concert with Sonu Nigam performed at the Royal Opera House, Covent Garden a few years ago.
