The other day, a friend of mine recomended these guys. At first, I was like "seriously, what the hell is this?" Then I listened to a few of their songs and they grew on me... now I have their song "Honey Bee" stuck in my head every friggin day.
I'm not always a fan of robots, but when I am, they're attractive with awesome voices.
Here's a link to their song
"Brass Goggles", the bouncing pug head will show you the way, ignore the chihuahua.
