I'm way out of my element in this dicussion, first off. Also, don't hammer me for the Beatles connection but Ravi Shankar's tribute to George Harrison "Arpan," is just amazing. Fantastic.
I haven't heard it but I'll look into it.
If you like sitar - check out the Nikhil Banerjee album I recommended or his performance of Raga Malkauns (another of my favorites). Nikhil was a different sort of performer - entirely unknown compared Ravi but they had the same teacher. Their styles are so different that it displays just how comprehensive the knowledge of their teacher must have been to teach such different styles. I'd say Nikhil is much more traditional in his exposition of the ragas. His number one influence was a singer named Amir Khan who came from and upheld a very noble, dignified tradition. Hence Nikhil's renditions of the various pieces is often deeply emotional and he has not modified his performances to suit a new audience (it seems to me from Ravi's releases that he only gives a few minutes for the most important part of the structure of a raag - the alap or introductory section - so that no one gets bored!).
One thing I like about Ravi's playing though is what I've seen referred to as a machine-gun style. Ustad Vilayat Khan also plays like that a bit - sometimes giving such a thunderous, climatic touch to his performance that can be exhilarating to hear.
