They are called original Sin from canada. The main singer is my cousin Deep and his friends all involved in this song. This is song is actually different from what i have in my cd. The guy who sings the chorus sounds differnt. Of all the Nepali rap i've heard they are no doubt the best out there. I have their whole album and to tell u the turth the rap is mind blowing. If anyone is intersted email me and i'll send you their songs. My personal fav is raja rani. I am telling you the just how the rap flow with the beat in that song is just amazing. Some of the other Nepali rap songs out there are just sad but these guys are definetly doing it the right way.
