I'll start this off by saying that I LOVE South Asian music and am pretty familiar with it: traditional music from various regions, Bollywood soundtracks, you name it.
Unfortunately, the first couple of tracks started this off badly for me. It's not the European/American influences that bothered me, since the 60's/70's Bollywood music that I like best mixes 60's rock stuff with classical Indian instrumentation all the time. The problem I guess is that the pop music that Shankar leans into here isn't the kind of pop music that I like. For me the first four songs were too much like Indian-flavored easy-listening music, and I didn't enjoy them at all.
But ending the first side, "Metamorphosis" was nice, and then all of the second side was lovely. "Sagar" is a gorgeous, 13-minute-long piece that seems to have a quiet little bass line in the background at times. "Dance Indra" felt fusion-y and interesting, and "Raghupati" was toe-tapping.
If I were just reviewing the second side of this album I'd give it 4 stars, but my attitude about the first side brings it down to a 3.
