The social networking site has ballooned into a multimedia phenomenon, with new and established bands alike promoting themselves through online word-of-mouth like never before.

Now the site has picked five of its best and brightest up-and-coming acts to travel the country for nearly two months on the MySpace Fall Tour, which kicks off in Dallas October 26 at The Door.

Arizona-based road dogs Greeley Estates and San Diego five-piece My American Heart – both fresh off the Vans Warped Tour – top the bill, along with A Change of Pace, Agent Sparks, and The Confession.

The bands’ youthful energy will be put to the test on the packed itinerary, which includes dates in nearly 45 cities. The tour wraps December 16 in Phoenix.
