I’ve used Noisetrade for years to find new music; you can download EPs and sometimes full albums for free, or in exchange for a tip of your choice. You do get signed up for the musician’s mailing list in exchange, but I’ve always found it more than worthwhile.
Now Noisetrade offers books, too, so I am extra excited that my publishers partnered with them to offer the first half of Mechanica as a free ebook right now. The offer will go away after a few weeks, but if you download the book you get to keep it forever. For free.
So read away, and please share this offer with your friends if you’re at all inclined. It doesn’t cost anything, and it’s a wonderful way to help spread the word.
