What ever happened to the good old days where men with varying voice parts dressed up as popcorn vendors with fancy white hats and canes singing tight harmonies to ladies on the street as they pass by? I assure you that they still exist, but you won't find them on YouTube with millions of hits!

A decade ago, A Cappella remained an untouched people group, a close community of like minded people that cared deeply about something no one else seemed to. But that's changed dramatically. NBC launched "The Sing Off" back in 2009. College a cappella groups all over the country/world fought for a place on the show. Glee, a show about adults who play students on TV and would most likely be involved in an a cappella "troupe" later in life, found smashing success. Pitch Perfect, I mean c'mon, who couldn't love this movie.

This year, Karmin released her single "Acapella" claiming it was produced entirely with the human voice. And that made it to the radio folks!

So what changed? A cappella got a face lift when it no longer became traditional, but innovative. Just look at Pentatonix. They can do dub step a cappella! DUB STEP! A Cappella has come a long way, and I believe that it will again return to it's niche of cult-like followers, but that day is not today. It hasn't even hit its potential!

So what do you think? Is a Cappella cool or not?
