I am a fan of a cappella groups. I like the harmony. I wish I could sing so well. I often like the songs, especially when it is classics.
Last week I came across a PBS special featuring Straight No Chaser They started as a college group, went their separate ways after school, and more recently regrouped. They were spotted on You Tube with a song and animation short called "The Christmas Can Can" which can currently be seen at their web site. You can also listen to a number of their Christmas tunes. Their songs are fun in addition to be being well done.
One of my favorite groups is the Tufts Beelzebubs. I first saw them when I was kid. I have seen them perform a couple of times here in the Carolinas. They get invited to some of the local invitationals. The other groups are good but then when the Bubs come on you realize there is a whole other level. Some groups are good in small venues with good acoustics but then as they get into larger auditoriums they begin to shout or they get too close to the microphone and it picks up every little pop and sputter. The Bubs come on and they stay back from the microphone and use breathing and projection to be heard. They also stay in tune and time more consistently.
I mention the Bubs because they made the NBC reality show The Sing Off which starts on Monday Dec 14th. I don't usually care for reality shows but I will try to watch some and see how the Bubs fare.
