“This three-volume behemoth purports to feature 350 individuals ‘who have had a significant influence on the development of music.” Many different styles are included in this set, such as rock/pop, opera, jazz, blues, and big band. The entries offer introductory material, career information, ‘affiliation’ (the group or groups the individual’s were part of), influence on music, and sources for further reading. Sometimes an image (in the style of an artist’s rendition) of the individual is included.
