There I absolutely ardent improv Musician am My "free" (that are those Improtheater players at her improvisational concerts musically accompany) and still'm Looking for new ideas that book For me the inspiration. So many new ideas, variations of already known ideas and suggestions for finding and developing your own exercises I have never get into or through a book. And since I also regularly with "my" Imrpotheatergruppen discourages music training, I'm just happy about any useful exercise. Surely found a great deal on the relevant sites on the net, but I have never found such a useful guide, especially in terms of improv theater and music. In addition, the book is also funny to read yet and I am too loose with my English skills.
Of course exercises and examples that do not suit me so, but that's my opinion to do so. And anyway I have to plow through a book so many times, because every time opens up something new. And that's exactly what makes me so on improvised performances fun.
But as I said already in the introduction: it is a book that serves a very specific niche and my luck is that in this niche I'm just artistic home.
