Wisdom of the Impulse

Packed with interesting and on-hands information, Tom's recent book, Wisdom of the Impulse: On the Nature of Musical Free Improvisation, is one of very few books on the subject of free improvisation, though there are countless books on jazz improvisation.
Free improvisation, as a practice, is historically quite recent, having begun around the mid to late 1950's, and only in the last two decades has it become a widespread practice. Wisdom discusses its early history as well as the practice today, and delves into theoretical issues involving the influences and processes, offering a useful and consistent terminology for understanding and communicating about free improvisation useful in any genre or style of music.
