Rainbow performed on this day in 1980 at the Falkoner Theater in Copenhagen, Denmark. It was the third date of the European leg of their Down To Earth tour.
Down To Earth, released the previous year, represented a dramatic shift in the group’s sound, beginning their turn to the AOR sound they fully implemented as the 80s went on. To sell this to their old fans and to bring in new, they had to work quite hard to sell it to both old and new fans.
The setlist of this concert had to walk this line, bringing in material both from their established work and from their newest album. The biggest showpiece was “Lost in Hollywood”, a number often extended to more than twenty minutes onstage thanks to the of instrumental breaks given to guitarist Ritchie Blackmore, keyboardist Don Airey, and drummer Cozy Powell. The song even looked ahead to the following album, Difficult to Cure, with its inclusion of Beethoven’s Ninth (arguably played better here than anywhere since).
This concert was recorded and is in circulation online.
The Falkoner Theater (also known as Falkoner Teatret and now known as Falkonersalen), the venue at which they played, must have been a very convenient one for the band; it was part of a larger center which also includes a hotel!
The whole center was built between 1957 and 1958, then renovated in 1989. For a time, it was the tallest high-rise in Denmark (source). The theater itself can hold about 2,000 people.
There are lists all over the internet of concerts which have taken place here; here are two of them. Some of the other concerts which have taken place here that are known to have been recorded can be found here.
