The grand prize is hard to pass up if you’re a music buff; in addition to the basics (plane tickets and a hotel room), the chosen blogger will receive a press pass for themselves as well as a three-day guest pass for a friend.

“Equal parts review and observation, your writing style needs to evoke the passion, the emotion and the fanaticism that comes with multi-day music festivals,” the web site says.

Judging the entries will be music-blogging superstars Stereogum, Scenestars, Chromewaves and Largehearted Boy. I like the idea of using bloggers to judge the entries instead of AT&T officials — it gives the contest more validity and reflects how the company respects the opinion of bloggers.

The ACL web site is getting ready to launch a variety of interactive features, too, such as free iPod guides, personalized schedules of events and even a Myspace page. The site currently features a message board for fans of the respected music festival.

ACL won’t be the only music festival receiving the web treatment. Mud-filled Bonnaroo, slated to start this weekend in Manchester, Tenn., will broadcast live online through AT&T’s “Blue Room” with webcasts, much like California’s Coachella did earlier this spring. Chicago’s Lollapalooza is also scheduled for an appearance from the Blue Room. If you’re heading to the Windy City this summer for the festival, I recommend checking the Blue Room out — I did last year when I attended the festival and it was a good way to beat the heat while seeing what was going in the entertainment world.

The ACL contest is just part of AT&T’s ongoing new media efforts, known as As the web site says, it’s “a network of top blogs and collection of influential editors designed to inform, as well as entertain.” The site contains blogging tips and a blog reader.
