The ingenuity goes to 11!

In 1984, a movie was released that still is considered one of the "awesomest" rock n' roll movies. The title? This is Spinal Tap, of course!

As cheesy and over-the-top as it was, the ridiculousness is what propelled the movie to be known. Well, that, and the Stonehenge scene.

The movie may not seem to have much to do with advertainment, but this article from Yahoo! News proves differently.

Originally, the faux-rock band Spinal Tap was just a parody of metal. Now, director Rob Reiner has filmed a 15-minute mockumentary continuing the tale of Spinal Tap, explaining what has happened to the members in the 20 years since the original film and why they chose to reunite.

The reason? Live Earth, a concert to raise awareness and money for global warming.

Not your typical form of advertainment, but it's a great way to get people to pay attention to the concert -- which has generally gotten more attention for the music than for the cause. It's definitely an interesting way to raise even more interest and more press. There's over 1000 videos tagged with "Spinal Tap" on YouTube, so we know people still love them. I can't wait to see if their performance at Live Earth leads to more people tuning in... as well as raising the number of audience members at the TriBeCa Film Festival this year, where it will be premiering in the opening sequence. After all, just look at these guys:

Really now, who wouldn't expect them to be advocates for a cause? ;)
