The GoPro camera has really revolutionized the way people record things, from concerts to extreme sports. Even if the video shot isn't officially used by GoPro for marketing, it's still great advertising for them. They're instantly recognizable.
While performing at a recent concert, country star Brad Paisely saw a fan in the front row with a GoPro, taking in all of the action. During a guitar solo, Paisely grabbed the camera with his left hand and just kept playing, while the GoPro recorded all of the action. This video gives you a really trippy look at what your fingers "see" while playing guitar.
This is probably viral marketing for GoPro, but who cares. It's badass!
