2) Midnight Sun was a Danish rock band in the 1970's.
Rainbow Band was formed in late 1969 as a supergroup consisting of Peer Frost (ex-Young Flowers), Lars Bisgaard (ex-Maxwells), Carsten Smedegaard (ex-Beefeaters), Bent Hesselmann and the former jazz players Niels Brønsted and Bo Stief (they had backed American jazz musicians at Copenhagen's Café Montmartre). The idea was to play jazz-influenced progressive rock in the style ofBurnin' Red Ivanhoe and Traffic's second album. These influences were strongly evident on their 1970 album. It's a very good effort, still very indicative of the hippie era. The rhythm section still produced the powerful 60s beat, forcing Peer Frost to squeeze out some of his best guitar solos. Lars Bisgaard was replaced by Allan Mortensen (ex-Tears) at the end of 1970. A Canadian group was already using the name Rainbow Band, which forced the Danish group to change their name into Midnight Sun in July 1971.
