This is a book every jazz musician and jazz fan should own. There is amusing trivia: How many people know that drum brushes were originally marketed as fly swatters? There are transcriptions of arrangements as well as of improvised solos. And of course there are biographical essays. The book is serious and scholarly and deep yet easily readable and entertaining.Also recommended: PENTATONIC SCALES FOR THE JAZZ-ROCK KEYBOARDIST by Jeff Burns
