In the preface to her complete volume on vocal jazz, Michele Weir writes "Jazz improvisation can be one of the most creative, adventurous, meaningful, and intrinsically rewarding things you can do in music."  Not only is she passionate about the art form, she has developed a step-by-step method that develops basic skills, teaches about hearing the changes, examines music theory, suggests group activities and provides a state-of-the-art recording with some of the best singers currently active in vocal jazz.  Interviews with 19 singers include Bobby McFerrin and Darmon Meader.  For singers, voice teachers, choral directors or students wanting to hone their skills or start from the beginning, this book is an absolute must.
