Adrian Mann has finally completed a project that he started at the age of 16. He has completed building the world's largest and longest piano that is over 18.5 long. This is certainly a giant feat to be achieved. It took him four long years of construction in a local barn in New Zealand to produce this colossus grand piano. His family is really proud of this massive musical instrument. He has definitely become something of a legend with this musical construction. Adrian's hard work has paid off! I'd like to play a few bars on this one.
