An important and practical publication for all drummers, written by the respected Czech drummer Martin Vajgl. The book presents 30 drumming etudes that the author considers the most important. Each etude is introduced with a short text and gives some hints and tips on how to play the etude in the best possible way. The book is thus a very practical tool for drum practice. The book also includes the address of the author's website, where all the etudes have their video recordings, so that you can get an idea of how they sound and how they should be played.  The text of the publication is in Czech.
