Lee is developing eleven new songs for an upcoming album called "Public Mayhem".
While video games like "Guitar Hero" celebrate classic rock, getting airplay for new rock music is especially difficult.
So Lee and producer Scott Humphrey have put online—for free—the skeletal foundation of the new songs at The Public Record.
One song a week can be downloaded. Then anyone in the world can submit additional instrumental music or vocals. Lee's team listens to each submission and will pick the best to add in what is the biggest global music collaboration in history.
How many submissions have they gotten?
"Thousands," says the veteran rocker, shaking his head in amazement.
In fact, they've had to upgrade their technology to handle all the traffic.
On the Web site you can see some videos of would-be collaborators, including one amazing four-year-old drummer.
The new album will be out early next year. Will anyone buy it, since everyone could get the base songs for free already? "These people are already telling their friends about it," says Lee of the contributors who've been named finalists. These contributors will not be paid, but they will get credit and have bragging rights in saying they were on Tommy Lee's "Public Mayhem".
