Rockheim

The idea for the museum goes back to 1998; the Ministry of Culture began planning eight years later and in 2007 Bratterøkaia AS won the commission to create it.

To roughly double the space available, a new sixth floor was added in the form of a cantilevered 'box', which is clad in glass decorated with reproductions of album covers and with changeable back-lighting provided by 13,000 individually controllable LEDs; the public can affect the colours by using cellphones.

It was headed by Arvid Esperø during planning and construction and until 2011, when Petter Myhr became the director;[11] he was succeeded in 2013 by Sissel Guttormsen.

The permanent exhibit, for which the lead designer was Canadian Stacey Spiegel,[2] takes the form of a journey through Norwegian music and cultural history from the 1950s to the present.

It occupies 320 square metres (3,400 sq ft) in the building's top-floor box, and devotes a room to each decade.
