In connection with the Hall of Fame induction at Rockheim, five time capsules with information about each artist have been put together, NRK Trøndelag reports.

Each time capsule, which is basically a steel container, contains pictures, biographies, discographies and recordings. It also contains a secret message to the future from (or on behalf of) the inductees.

The capsules will be on display at Rockheim over the next year, before they are sealed shut. They will then be placed somewhere in Trondheim for the next 50 years, before they are to be opened.

So mark your calendars folks, and be prepared for a secret message from a-ha sometime in 2062.
