I worked with Giuseppe Sorbello in designing and printing his book on vocal training for the performing arts after I had designed and developed his website. Giuseppe had written this book over many years and hand drawn the images that ended up inside the book. Giuseppe had an idea for the front cover which included somehow incorporating music into the title itself.
It was a delight to work on this project and see it go on to become available through university bookstores.
I often use AppSumo to get great deals on graphic and development software. Now you can get $10 (after your first purchase) when you sign up at AppSumo too. Full disclosure, I also get $10.
