Rainbow was formed by Ritchie Blackmore in 1975 after he left Deep Purple at the height of their fame. http://smarturl.it/RainbowLiveGerdvd They were instantly successful and released a string of hit albums, with an ever changing line-up, between 1975 and 1983 when Blackmore broke up the group to join the reformed Deep Purple.
