"Jerusalem" is a Christian rock band, based in Sweden that was founded around 1975 by Ulf Christiansson. They are widely viewed as the first Christian band with a hard rock sound.
When the band first toured in the mid-1970's in Sweden, their combination of Christian lyrics with a hard rock sound was very controversial. Hard rock was connected to drugs, aggression and the Devil, and the band was only permitted to perform at a few churches.
Jerusalem's message was primarily aimed at youth, with their lyrics describing the band's relationship to God in an ordinary, but radical way. The concerts have been described as a series of revival meetings.
Over time, Jerusalem gained broader acceptance, and after three years of touring record companies began making offers to record the band. The Christian record company Prim signed Jersualem, without much expectation of success. However, the band's self-titled first album "Jerusalem" became an instant hit among Christian listeners, and within the first six months the record sold 20 000 copies, unheard of within the genre of Christian rock in Europe.
