    Sam Tsui and Kurt are awesome guys, and doesn’t metter if they aren’t on TV all day. I just love their works because Sam have the most beautifull voice that I have ever seen and Kurt…Well… KURT IS AMAZING IN EVERYTHING HE DOES! As director, as a piano player, as a guitar player, as a singer, even as a CELLPHONE COMPOSER! So, in my point of view, they can not be the most talented people in the world or the most known but they are good and they have fun doing this :D
