if you are a computer music producer this aint a book for u. only if you can read notations you can follow this book...
examples that i tought i will learn something from them, are not written and displayed in popular piano roll/step sequencer view like in Michael Hewitt's book. so if your are using softwares like fl studio ableton etc, and you want to expand your knowledge on making grooves, this might get tricky.
another star down for this book is because of the writer's constantly playing "journalism", writing about unnecesery information.
somehow i gave up from reading books this kind subject...
but, if you can read notation and want to read about stuff that not relate to MAKING music , this book is for you.
i want to point out that book is all about groove, but NOT about MAKING it all the time, sometimes it goes too far, too philosophicaly.
