Can you recognize these people ?
At least u should know the first and second picture right ?
Judging by their appearance ?
Still no answer ?
Ok they are ( from left to right ) Ludwig von Beethoven, Wolfgang Amadeus Mozart, Pyottr Ilyitch Tchaikovski and Sergei Rachmaninoff

Its true that they dont dance around half-naked like Britney or Blow your eardrum with excessive shouting like any rock musicians..
But they create symphonic and true balance of music and rhythm..
Their music is the food of soul, they soothe our anger, embrace us when we feel weak, etc.. etc..
