Someone(s) I think Is cool

So this post is all about a group I think is super cool but in particular my favorite video by them. I encourage you all to check out this video and others by them! http://www.youtube.com/watch?v=lExW80sXsHs
The video is called "Evolution of music" and its by one of my favorite A Capella groups, Pentatonix. For those of you who do not know, A Capella is basically just music without instrument accompaniment, so in A Capella songs it is just completely singing, making instrument noises or both (Ever watch the movie pitch perfect?). This video travels all the way back to 11th century and goes up into the 2010's. Throughout the video you experience 4 minutes of some of the best songs in all those era's. It is amazing to see how far music has come and how it got there. What most people do not realize is that pop music does not refer to all the bubblegum music playing right now but it refers to music that is popular in any generation and bubblegum just so happens to be it right now (That means you could technically call Mozart pop music) The songs are all pretty recognizable (unless you live under a rock in which case how did you make it to my blog?) They have lots of other covers of different songs but this is my favorite. I honestly love A Capella and wish that the groups got more cred and fame because to be in a group you HAVE to be a good singer. One thing just in particular about this video is if you watch closely you can see the color and quality of the video change as you progress through history.
