It is definitely interesting, but I don't see how it is very different than a good performance in the Jazz style. Of course, I think people like Wynton Marsalis are just masterful, so I guess this is equivalent in the Indian style?
Yeah, I would say that Jazz is definitely the closest thing Western music has to Indian music -- I think the big differences lie in the genealogy in that Jazz and Blues tried to bring a lot of improvisation into an otherwise rigid system built for large ensembles whereas Indian classical music was built from the ground up a few thousand years ago (though it's been through organizational reworkings, particularly around the 16th century) with improvisation and extemporaneous performance by individual performers as a fundamental aspect, so the encouragement for improvisation is far more... systematic, for lack of a better word. You take that particular song for instance, for which the raw composition with all of its expressly written sangatis (variations) probably add up to about 3 or 4 minutes... instead, he made it into a sea of variations and swara prstharas that covered some 25 minutes not including the alapana. Include the fact that he is as precise as he is even with his brighas (what you might call trilling), which are done at a speed relative to the tempo. But for him, and people who have since followed his example, that's pretty normal treatment for the song that becomes the "main song" of a concert (excluding the RTP, which is a different story).
A lot of the things that people *think* are the case with Indian classical music are there because of the fact that the Western audience got exposure to the likes of Ravi Shankar and Alla Rakha at a time when the audience receptive to new styles of music were all doing psychotropic drugs. What you're hearing is in fact closer to the genuine nature of Indian classical music, though after theoretical study work over the course of the 20th century has really transformed the complexity by leaps and bounds.
Part of the "hypnotic" and "meditative" aspects that everybody thinks of come from the fact that the fundamental definition of a note is different. In western music, it's a point -- a pitch. In Indian music, all notes are a set of shapes that can include hard terminal points derived from 22 pitches (per octave) or even microtonal inflections and so on. And this is partly why I don't like how people often refer to "gamakas" as "embellishments" because the word "embellishment" seems to imply that they're optional. They're very much NOT.
Secondly, more people in the West are familiar with the North Indian style (a la Ravi Shankar) than with the South Indian style, which is what you heard. Admittedly, the North Indian style is more amenable to fusion and such as it has already taken in influence from other styles over the years. Nonetheless, there are also rhythmic differences as well -- tabla players actually keep the count apparent as they play, whereas mridangam players don't, so you'll often see that in Hindustani (North Indian) performances, lead performers don't count the beat cycle as they go, while Carnatic (South Indian) performers do. That means that it's a lot easier for someone less familiar with the music to read the rhythm. Carnatic rhythms are much harder to read for someone unfamiliar because the percussionists are given so much free rein... For instance, this guy on the Kanjira --
http://www.youtube.com/watch?v=GPPBoei6oCs Yeah, I know it tells you what the talam is, but assuming you don't know can you guess how many beats to a cycle it is? Or when he hits those really fast quick strokes near the end (around 3:06-ish?), how many strokes per beat that's equivalent to?
Another thing is that there's a structural system in Hindustani music that centers around repetition at several speeds, so you tend to hear a lot of sloooowww starts, which makes people think that it's a meditative experience, but they miss out on what comes further down the line.
Then of course, you have the fact that Hinduism is an introspective religion by nature, and that makes people assume that the music which is often devotional in content (not necessarily, though), must also be introspective. The reality is that the introspective nature of Hinduism affected things at a music theory level. You think about Western religion involving people gathering in prayer and speaking of the glory of God in unison, and it's not surprising that Western classical music should have developed in such a way as to support many voices. Hence why you have orchestras and choirs. Conversely, Hinduism is all about individual exploration and interpretation of the glory of God, so what does one individual have at hand to evoke the praises of God? Usually, it's his/her one voice. So it shouldn't come as any surprise that Indian classical music tended to be built around the extents of what a single singing voice can do. And that's why accompanists tend to act in such a way as to support the vocalist rather than try to take a course of their own. Also, it's why the violin was such a well-received instrument for accompanying a lead performer, because it's just about as flexible.
You look at the way Carnatic violinists learn to play (and I went through this as well), we always learn to sing the piece before we play it. Similarly we control our bowing to "pronounce" the syllables (though the violinist in that particular recording is better at it than anybody, and he did that whole song not including the alapana on one string with one finger)... a consonant sound starting with "k" for instance is a rough sound by nature, so on those syllables you start your bow with an instant of heightened pressure on the strings... a syllable starting on a raw vowel "ah" would be smooth but sudden, you adjust accordingly. "s" would yield a smooth acceleration of the bow in the first fraction of a second and so on...
Personally I think there is a lot to be said for the gift of writing theoretically complex music that is enjoyable to a large audience. Take Wynton Marsalis as a counter example - extreme depth in his understanding and mastery and control over his instrument, but not appreciated by a wide audience.
Yeah, I find it easy to think that Carnatic and Hindustani music is easily appreciated by many because that's how it is for many within India. As much as it is a deeply technical system, you look around in the right parts of India (i.e. the areas that aren't so "westernized"), and just about everybody knows a hell of a lot about music, and often times not just Indian music. You go to Chennai (where the Music Academy happens to be), and you could walk past a homeless guy in the street who could lecture you on ragamalika(modal shifts) and swarabedham(tonic shifts). Here in the western world, we don't have our direct descendants of Mozart or Bach here nor would we know where to look to find them... but you go to the music cities of India like Tanjore, and you couldn't go very far
without finding someone of such a heritage.
