The Rifftides staff has added Marshall Bowden’s Jazzitude web site to Other Places in the right-hand column. Befitting its Louisiana origin, Jazzitude is a gumbo of a site. On the menu: news, reviews, features and history sections. If the free enterprise road to the internet future is advertising, Bowden is paving it with a profusion of links to books, DVDs, CDs, posters, instruments, equipment and sheet music. His menu doesn’t trap you in the ads, though. It allows navigation to what interests you.
