This doesn't fall into the category of "classical" Indian music, but if you like that influence in your music, you might check out the CDs "Jubilee" (Harry Manx and Kevin Breit) and "Wise and Otherwise" (Harry Manx) for music that melds Indian influences with the blues.
Indian Sitar Stuff
While somewhat alone at the time, I rather enjoyed some of the sitar and sitar-influenced guitar work George brought to some of the Beatles songs. Just recently, I found an old Ravi Shankar LP "Three Ragas" on Pacific Jazz and really like many parts of that. Can people suggest pressings (LP's) of other similar instrumental-only Indian music featuring sitar. I am not huge on vocal pieces. Maybe if I understood. ;-)
