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. ;-)
