He also attended and performed in a series of three concerts celebrating the 25th anniversary of "The Legend of Zelda" series in late 2011. He performed piano with the American rock band Imagine Dragons live at The Game Awards 2014 ceremony in December 2014. Kondo's music for "Super Mario Bros." was designed around the feeling of motion that mirrors the player's physical experience. This followed the philosophy of series creator and designer, Shigeru Miyamoto, who demanded that audio for the game be made "with substance" and are synchronized with elements of the game. As a result, Kondo based a number of the score around genres that are primary used for dancing, such as Latin music and the waltz. In the first "The Legend of Zelda", Kondo juxtaposes the game's overworld theme with the theme that plays in dungeons. Kondo remarked on the importance of projecting distinct characters through music, so that players know almost immediately where they are within the game. Kondo used this contrast in other games he worked on, including "Super Mario Bros."
