The band's first album, Softly, was released in Finland in August 2004 and reached Top 50 on the national album chart with promising reviews in music papers, magazines and web magazines in Europe. Finland's top nationwide rock radio network YleX chose Softly as the album of the week in August 2004. The singer and bass guitarist, Mikko Herranen, has produced all of the band's recordings, including three full-length albums, two EPs and five singles.

In spring 2011, RUST decided to disband. The final performance was in Helsinki on May 25, 2011.
