The site is accessible from the AOL Music main page and its goal is twofold: First, to be a one-stop destination for music fans looking to follow their favorite bands/artists on tour. And second, to provide a resource for music labels to track the popularity of a particular artist or tour beyond ticket sales.

As the exclusive sponsor, American Express is provided with "prominent placement" on the site and cardholders are presented with special discounts to buy tickets, according to an AOL spokesman.

"We're always looking to find new and innovative ways to help music fans stay current on their favorite artists and bands," said AOL Music Vice President Bill Crandall in a statement. "Tour Tracker provides music fans an ongoing outlet to follow and discuss an artist throughout a tour or simply find comprehensive listings for which artists--mainstream or indie--are playing hometown on any given night."

Fans can search nationally by artist, location and date. They can track an artist throughout the entirety of a tour. Music fans who are traveling can find an extensive catalog of show listings for any U.S. city on any specific date.

JamBase powered listings provides extensive concert listings--including indie bands and smaller venues and theaters with MapQuest-powered maps and directions to venue locations.
