Query: Some of the better info out there

This book is over 80 years old, but its subject is many centuries old- so that is not really an issue. The descriptions can be a bit esoteric at times. It's fairly short. It is not exactly a page turner, the some parts can seem repetitive if you are reading big chunks without listening to the music as well. However, I think it is one of the best books on Indian music I've found in English. If you are looking for a good guide to assist in listening to and understanding great classical Indian music, this book serves that purpose very well. If you are looking for a book that includes contemptorary Indian musicians and has pictures of George Harrison, there are other books out there that can offer that kind of thing.
