Sam Tsui

Sam Tsui started posting cover songs on YouTube around 2009, with a version of Jason Mraz's "Lucky" gaining attention. He built an audience there with vocal arrangements that often leaned into pop and R&B, working on tracks like "Heaven" and "Impatience." His early work included the "Summer Medley 2011," which pulled together various pop songs into a single piece.

He put out his first album, "Make It Up," in 2010, followed by others like "Cassette" and "Something Like Love." The songs tend to be straightforward pop with clean production, sometimes touching on acoustic or R&B feels. You can hear that in tracks such as "Grey Area" and "One More Night."

Over time, he has done collaborations with other singers who came up through similar online channels, including Kina Grannis and Tori Kelly. The covers kept coming, too, like his take on Whitney Houston's "I Wanna Dance With Somebody." It's mostly been about vocal harmony and pop songcraft, without much shift from that core approach.
