Ah well, he and I didn't really have any talent, nor did we know any talented musicians, and our vision happened before the age of the Internet, when the world's time and attention was simply not available the way it is today. For us, the idea was destined to collapse in on itself, unrealized.
Scott Bradlee, on the other hand, the founder and band leader of Postmodern Jukebox, seems to be nothing short of an alchemist on the piano, and his assemblage of musicians and vocalists, the collective talent he brings together, generally achieves a brilliance in the way of the sun shining, and has helped make PMJ among the most successful YouTube "sensations" of all time. They are currently touring the world, a string of live performances that no doubt are quite a spectacle (just might have to check them out, actually).
PMJ's popularity isn't really hard to understand; I think everyone - at least everyone for whom music is more than just background noise - has this idea at some point in their lives. There is a ton of these available on YouTube, each one a musical gem, and each perfect either for practicing my air piano (I'm getting better!), or, in the case of their version of Miley Cyrus's "We Can't Stop", just astonishingly beautiful to listen to.
