A.R.Rahman and Vishal Bhardwaj are probably my two most favourite film music directors at the moment, but apart from the likes of Gulzar, I cannot think of their social worlds having overlapped in any significant way. (Musically, they share much in common: a certain originality, an unconventional spirit, an ability to traverse regions and moods, the courage to mix a bass guitar with a sitar.)
Which is why I was very interested to read that Rekha Bhardwaj, Vishal's wife, has sung for Rahman in his upcoming Dilli 6. In the film world, Rekha, to my mind, is a lot like Vishal: hugely underrated and hugely under-feted. I have been a fan of hers ever since I first heard her in Maqbool ('rone do, jiyaa kare'). Compare that voice and aspect with her songs in Omkara ('namak', 'laakaD jal ke') and No Smoking ('phuu.nk de'). Her capacities for modulation and voice are outstanding. Rahman's songsheets, which have seen an incredibly wide range of singers, add one more songbird to their notes.
