David Usher (born April 24, 1966) is a British-born Canadian musician, best-selling author, keynote speaker, and activist best known as the front man for the band Moist.

[2] He has lived in various places such as Malaysia, New York City, California and Thailand since early childhood, before his family settled in Kingston, Ontario.

They followed this with a compilation album and DVD in 2001, titled Machine Punch Through: The Singles Collection, and thereafter entered a hiatus period that would last twelve years.

The song "Alone in the Universe" was released as the first single, and the album featured collaborations with some members of Moist and with several figures of the Canadian music scene including Jagori Tanna and Bruce Gordon of I Mother Earth, Gord Sinclair of The Tragically Hip, and the rapper Snow.

Usher's third solo album, Hallucinations, came out in 2003, and includes a cover of the Manic Street Preachers song "If You Tolerate This Your Children Will Be Next".

The Mile End Sessions is composed mostly of previously released songs re-recorded in acoustic arrangements, is produced by Moist member Jonathan Gallivan, contains Usher's first French-language recording, and features contributions from Marie-Mai and Cœur de pirate.

Throughout his musical career, Usher has sold more than 1.4 million albums, won four Juno Awards and had several #1 singles singing in English, French, and Thai.

[10] He is featured in the 2001 MuchMusic special Musicians in the WarZone, a humanitarian documentary directed by filmmaker Liz Marshall, in which he journeys to the northern border of Thailand to visit a large Burmese refugee community.
