I found this video and oh my god I love it. He shows the importance of the beat of the drum by showing its vitality through decades and decades of popular songs. He starts with Elvis then goes through the Beatles, Michael Jackson, the Rolling Stones, Nirvana, and ends with modern day bands such as Lady Gaga and Skrillex.
This video is kind of like a quick History of Rock Lesson. I took a History of Rock class in college and this kind of wraps up what we did in three months. Check out and let me know what you think. Do you know of anymore like this?
