Chicago had its cows. Toronto had its moose. New York had its taxis.San Francisco had its hearts. And...Phoenix has its guitars.

It's GuitarMania, and it's a fund-raiser for Big Brothers & Big Sisters in "the valley." We toured the largest central collection of them in Phoenix, that being in front of America West Arena and by Chase Field (formerly Bank One Ballpark). The fiberglass guitars are all very cool and are some even are made to honor celebrities such as Stevie Nicks, Alice Cooper and Wayne Gretzky . All are done in themes that range from the straighforward to the abstract. The video speaks for itself.

As more companies take to the Web to launch new musical talent (including the bands themselves), there will be an even greater need for the tools of searching, sharing and discovery.

Clear Channel Communications on Tuesday is expected to launch an online service offering hundreds of songs and music videos from new and unsigned artists as part of a larger foray onto the Web.

The largest U.S. radio conglomerate, which owns about 1,200 radio stations across the country, also has a deal with GarageBand.com, a site for new musicians, to boost access to new artists material.

At launch, the service, called NEW!, will feature nearly 100 emerging artists from music labels including Atlantic, Capitol, Columbia Warner Bros, and Def Jam, along with unsigned acts every 90 days.

About 16 featured artists will have a home video, five songs and a link to the artists' web site featured on any number of Clear Channel's local radio station web sites.

Fifty GarageBand.com artists will also have five songs, a photo and artists information on Clear Channel's sites.
