Major League Baseball continues to appeal to music fans, this time linking up with the Projekt Revolution tour in a new promotion. Random fans who attend the 24-date tour will receive a lanyard that can be exchanged at Champs Sports stores for a USB wristband featuring four unreleased MP3s by Linkin Park plus five other acts from the Projekt line up. If you’re not one of the random fans who receive the lanyard, you too can get the USB wristband simply by buying $50 worth of MLB merchandise at the store. MLB will also have a presence at the tour itself, tagging along with a tractor-trailer filled with pitching machines, batting cages and video game kiosks. As previously reported, MLB will stage a free Bon Jovi concert on July 12th in New York’s Central Park to commemorate this year’s All-Star Game, the last to be played in this incarnation of Yankee Stadium.
