To continue it's 'balls to the wall' approach to a product launch, Windows Phone will offer up concerts by Katy Perry and Maroon 5.

According to the article, via Billboard:

Microsoft and AT&T will launch the new Windows Phone with free concerts featuring Katy Perry at the Roseland Ballroom in New York, and Maroon 5 at the Fillmore in San Francisco on Nov. 8, the company announces today. Tickets are available only at select AT&T stores in San Francisco and New York on the day of the shows, also the day the Windows Phone launches.

One of the reasons why this is even being done, especially for a PHONE launch is the Zune integration that's a highlight of the new Windows Phone experience. I must say it's quite awesome that Zune is in such high regard that folks on the East and West Coasts will be treated to some great music.

The Windows Phone love of music doesn't stop there however:

Additionally, Windows Phone is a sponsor for the Billboard Touring Conference Showcase, produced by Live Nation and to be held at the Gramercy Theater in New York on Nov. 3. On the bill are the Gracious Few, Sick Puppies, the Postelles, A Place to Bury Strangers, the London Souls, Bad Rabbits and Laura Warshauer.

It's looking like Microsoft is really pumping that marketing cash into some really cool things for launch.
