Indian Sitar Stuff

I second the Ali Akbar Khan - also check out the CD entitled RAIN on ECM label.

Although not sitar you might try "Gathering Rain Clouds" and "Saradamani" by V.M. Bhatt. Both are on Water Lily vinyl and are superb quality recordings. Here's a link to Bhatt's AMG info.

I second the Waterlily CD's. Check out Ali Akbar Khan's 2 SACD set on the Waterlilly label, also look for reissues of connoiser society recordings under Ali Akbar Khans own label - AMMP. On EMI vinyl look for Ustad Vilayat Khan. For Ustad Vilyat Khan on CD's look for India Archive Music & Navras CD's. I also suggest Pt. Nikhil Baneerje his bio/discography can be found on Raga Records site. Happy listening.

I will pass on the CD's, but maybe this info is of help to others.

Anyone know of a site (other than E-Bay) or two from which to seek the vinyl offerinfs (old or new)?

unfortunately ebay is the best place to find the out of print sitar LPs, and especially unfortunately, the best ones (Vilayat Khan on Indian EMI) are very sought-after and can go for big bucks if they're mint.
I am a big Indian music fan (and student of) and, if it's the music you're after, I'd reconsider your vinyl bias. I am a vinylphile and totally understand your preference, but two things about Indian music make CDs a good thing: huge dynamic changes from nearly silent to loud and LONG compositions. That being said, here are a couple CD recommendations which I would consider essential if you want to get into true Indian classical (not fusion):
The Raga Guide on Nimbus - a 4 CD set that features sarod, flute and male and female vocals, and has a great book
Raga Yaman by Z.M.Dagar (also on Nimbus) - this is very subtle contemplative ancient music played on the Rudra Vina - the ancestor of the sitar family
Happy hunting!
