Sam Tsui, hailed as an Internet singing sensation and one of YouTube's hottest cover artists, joins "The Sing-Off" in Season 3 as its behind-the-scenes correspondent.

Tsui has amassed nearly 250 million views in a little over two years on YouTube. First recognized along with his producing partner Kurt Schneider for their covers of Journey's "Don't Stop Believing" and a Michael Jackson medley (both of which featured a duplicated ensemble of Tsui performing tight a cappella harmonies,) the team began building a worldwide fan base with consistently inventive content. From musically intricate pop medleys to fully produced music video-style content, Tsui's voice and style have taken over the internet with covers and re-arrangements of artists from Adele to John Lennon to Lady Gaga.

A 2011 graduate of Yale University with a degree in Classical Greek, Tsui taught himself to sing and play piano in a household with an American mom who taught high school chorus and a Hong-Kong born dad whose own mother is a Chinese Opera singer. His overnight success with fellow college mate and childhood neighbor Kurt Schneider not only made the two instant Internet celebrities, but also landed them television appearances on "World News Tonight" and featured performances on "The Oprah Winfrey Show" and "The Ellen DeGeneres Show." Tsui has also appeared in print in both InStyle Magazine and TIME. His international fan base is equally huge, with the duo's work featured on national television in the Philippines, on Swedish radio stations and across the globe.

Not only a powerful vocalist but a mature songwriter as well, with his original songs on YouTube garnering views comparable to many of his covers, Tsui has just moved to Los Angeles in order to set out on his pop career.
