Sin Fang is the solo music project by Icelandic musician Sindri Már Sigfússon.

Sigfússon founded the band Seabear in 2000. Although Seabear was initially conceived as a solo project, Sigfússon kept adding members to his band.

In 2008, he released his debut solo album Clangour under the name Sin Fang Bous.

After shortening the artist name, Sin Fang has since released four full-length albums: Summer Echoes in 2011, Flowers in 2013, Spaceland in 2016 and Team Dreams in 2018.
