I had come across one of their songs – “Welcome to India” sometime back. It was hilarious :D . MC Vikram and LudaKrishna are 2 Malayalees in the US setting new trends in rap. Although they rap mainly in English they do spice up their work with a decent dose of Malayalam.

This is one of their videos in google. It goes “I want to find a nice girl; a curry & rice girl!” ;) Their ‘INDIAN’ised English and ‘LAACAL’ costume is really hilarious.
