Trad, Gras Och Stenar

Träd, Gräs & Stenar ("Trees, Grass and Stones") is a Swedish rock band formed in 1969, from previous incarnations Pärson Sound, International Harvester and Harvester. The group was one of the front acts of the Swedish progg scene, although noticeably less political than their contemporary counterparts.

This constellation, which were playing an experimental style of psychedelic rock never released any official records, although a collection of recordings from 1967-1968 were released as the double CD Pärson Sound (1967-68) in 2001 and as a 3 LP Deluxe box set in 2010. In August 1968 the band changed their name to "International Harvester" and later the same year their debut album Sov gott Rose-Marie was released. In 1969 the name was shortened to "Harvester", under which the album Hemåt was released.
