Despite their lack of commercial success, Kingdom Come's 1973 album Journey has received generally positive retrospective reviews from critics.
[3] After the collapse of The Crazy World of Arthur Brown in 1969, when keyboardist Vincent Crane and drummer Carl Palmer left to eventually form Atomic Rooster, Brown worked with a varied group of musicians on projects called Strangelands, Puddletown Express, and (briefly) the Captain Beefheart-influenced Rustic Hinge, before finding the musicians who would make up Kingdom Come.
Harris left shortly before the recording of their final album, Journey, and was replaced by American keyboard and synthesizer player Victor Peraino.
For synthesizers Kingdom Come used the VCS3, and the Mellotron and theremin also figured prominently in the group's repertoire, especially after the addition of Victor Peraino in the band's line-up.
A number of factors contributed to the end of Kingdom Come, including mediocre album sales, critical disdain, the revolving door membership of the band, and Brown's frustration with the music business in general.
