Sony Media Software - Free Loop Sampler and Calendar
Get this CD. It comes with Acid Xpress and a whole bunch of music loop stuff. I don't like computer music, but it is quite possible to mix up some nice background music or rhythm lines for harp. You can download all of it from the Sony site, but it is nice to have it on CD and it is the right price - free.

Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.
