YouTube superstar Sam Tsui has amazing vocals, but the full effect of his performances would be impossible without some inspired video editing. Tsui does all the singing, but Kurt Hugo Schneider finesses Tsui’s a cappella efforts into a group act. Schneider assembles and synchronizes individual video clips of Tsui singing into ‘group’ performances. Schneider also creates the song arrangements.

Trend Hunter Shelby Walsh wrote about Sam Tsui and Kurt Hugo Schneider in December 2009. Since then, the pair has gained popularity including an appearance on Oprah.

Check out the video above to learn how the pair achieved the magic of YouTube fame. Their Michael Jackson Medley has been viewed over five million times since last July.
