Ben Frost (born 1980 in Melbourne Australia, now based in Reykjavík, Iceland) is a musician, composer and producer, whose early work included the independently released ambient electronic Ep Music for Sad Children (2000) and whose early collaborations were with fellow Australian artists such as David Bridie and rock band Something for Kate. However Frost is probably most widely recognized for his experimental music drawing widely on influences of minimalism, post-punk, black metal and noise best demonstrated on the 2007 release "Theory of Machines".

Frost's compositional catalogue includes Music for Sad Children (2001, independently produced and released), the ambient guitar exploration Steel Wound (2003, and reissued in 2007), Room40), described by Pitchfork Media as "an exemplary ambient experience", and the widely critically acclaimed LP 'Theory of Machines' on the Icelandic record label Bedroom Community, an album which earned Frost huge critical acclaim and it could be said, cemented his place as an artist on the global stage.
