I don't know the first book but I have a copy of This Business of Music by Shemel & Krasilovsky 4th Edition. Not sure if it's the same book as you're referring too. That is a book everyone who's serious about this business should have on their shelves and should have read at least once, to get a good understanding of the basic business practices in the music industry. It's handy to refer back to it on occasion as well. I actually had 2 copies at one time but gave one of my copies to a young musician who was asking me a lot of questions so I figured he would benefit from the book and I didn't need two copies on my shelf.

I think This Business of Music is out of print now.
