After reading the title I expected to learn more about actually MIXING the kick and bass together. IMHO this focusses a lot on what you can do to each of them in solo, but unfortunately not so much on how you get both elements to form a tight and professional sounding low-end. Furthermore, some of the techniques discussed weren't really applied to a real world example, instead it was just shown how to achieve a certain thing with the plug-in at hand. I didn't find that to be very useful.
However, I still picked up a few tips and tricks here and there. Thank you!
