The way OS Arunji, says "shyam shyam shyam" the aakar etc. is ditto Pt. Jasraj. The anu-nasiks(nasals) also reminded me of Jasraj. Ofcourse he maintains his own creative distinctness. Interesting also is the way the audience responded, moving and shaking and clapping, he seemed to have cast a hypnotic spell on his audience. They dint seem like classic-Mylapore-wale-rasikas. This goes a long way to show how effective Arunji is.
More power to you Arunji. We love your music. Some songs that he sang are very popular in north india and my mind kept going back to Pt. Bhimsen and Lata and their renditions of the same. But Arunji has energy, and boy he is totally immersed in his music.He deserves at least Padma Bhushan.
Do watch the other parts of this performance which he gave at Margazhi'09. They have been uploaded as a playlist by the same channel.
Btw btw, I read on the web that Arunji has launched his album of Tamil-gazhal. You read it right Tam-gaz ;)
