I have the Electronic Projects for Musicians and I agree, its hard to get some of the parts... for a newer book with easy to find parts and some fun projects try Handmade Electronic Music by Nicolas Collins http://www.amazon.com/Handmade-Electron … 0415975921
(biotek and i saw him do a demo/book release in chicago
there is another edition coming out soon.
I'm pretty fond of the ' Evil Genius ' series. All of their books have thorough project descriptions and parts listings. Here's a link to one of their books , but you can easily get drawn into a whole wormhole of others on amazon. They have a nice sense of humor as well! Their spy book is loads of fun

I HIGHLY recommend anything Forrest Mims (also mentioned!)
Practical Electronics for Inventors is quite a resource, better to use as reference material than a getting started on projects type book. http://www.amazon.com/Practical-Electro … 0071452818
For kits, this website - solarbotics - offers a lot of great little build-yourself robots and things to get you started

Finally, I took a class in basic analog circuits and this is our syllabus. there are links to a LOT of great resources just on that. Starting at the very basics, like soldering and using a multimeter.... if you want to do anything electronics... you must get very friendly with your multimeter, its essential! and better yet a 'scope (looks cooler anyway) ! you need to use it to identify where/what the problems are (in a faulty synth or any other circuit) before you start to fix them. there are some classes in there that deal with audio ....

have fun !
edit : just thought of one other tip... if you want to be confident you're really getting it - pick an online kit and buy two of them. the first one, put together on their given printed circuit board. when that works, throw away the PCB on the second kit and just put it together on a breadboard. it helps.
