Well from what i know till now is that basically Mc(short for Master of Ceremonies)is a Rapping Music style that had originated during the late 70's and 80's but is now gaining pouplarity in the form of Hip-Hop And similar genres.It is very different from turntables as it is nowhere near to it infact it is a sort of music genre and thats exactly what Mike Shinoda is currently the Mc And the supporting vocalist in The Now Split Linkin Park band.well abut it being practised in India have no idea at all infact havent heard any big rappers here so can't tell u if there is any place for learning it over here.ok hope this helps.peace.
