Jazz historian Ted Gioia has launched an ambitious new web site. It is called Jazz.com. It encompasses a blog, a forum and an interview section. Its Encyclopedia of Jazz Musicians feature has enormous potential for listeners, musicians and researchers, indeed for the entire jazz community. In its initial appearance, the Encyclopedia is missing a number of notable musicians, but it solicits readers to suggest improvements. As it expands and undergoes refinements, it could become invaluable. Welcome to the web, jazz.com.
