From the moment we are born, we hear, hear and feel all kinds of sounds,

some pure noise, but many end up joining to form chords, 
melodies, songs, orchestras and ultimately, ... SENSATIONS.
  

The fidelity of the recreation of that original work, music or score, as his 
composer dreamed of it at that moment of pure creativity, ... at the time, 
when he composed in harmony or plunged in pure torment, ... your world, transferred 
to ours, using our own time machine to achieve one of our 
main objectives, call it mission or dream.
