What I really like about this video is how Bowers 1) gives us a taste of all these styles with musical examples, 2) does it in real time, and 3) plays it all himself. What a performance!
While I disagree with the reductiveness of the video (such as the claim that one person inviting ragtime or the stride style, for example), I understand that in the short time they had, they gave their audience of lot of really interesting information. They also understandably spend much more time on the present day than warranted, and perhaps too much time on Herbie Hancock, important as he is.
For more commentary on the video, I first saw the video linked from the NPR Jazz blog, a Blog Supreme by Patrick Jarenwattananon. Enjoy!
Vocab: ragtime, stride
