While visiting with some friends over the weekend, they shared a music video they randomly came across on the tube of you. It is a band called "Steam Powered Giraffe".
According to the wikipedia page, they were formed in 2008 and is popular in the steampunk subculture. They are also trained as mimes, which is evident in their antics as steam powered robots. They have also created a backstory for the band, which I also find interesting.
Their harmonizing is quite amazing as well as the voice range of the guitar player.
I can't say that I would want to listen to them all the time, but they are a nice change of pace.
