The first edition included a compact cassette with unreleased tracks by Troll, Uppsala, Eskaton and other bands whose albums were difficult to obtain due to poor or complete lack of music management.
Bernard Gueffier commented on this in an interview in 2014 as follows: […] in the 80’s, I observed that all record companies forgot about Progressive Rock and turned to more profitable styles such as Punk or New Wave.
[1] The first activity was to collect the stock of non-distributed albums by French artists in the fields of progressive rock, jazz-rock/fusion and new age music.
At the time, this catalogue comprised about one hundred titles and consisted mainly of in-house productions that became collectors' items: DÜN, Falstaff, Synopsis, Eider Stellaire, Nuance were some of the first bands to sell their albums this way.
From the beginning, Musea was keen to treat each album as a complete work, where music, cover, concept and lyrics should be part of a coherent whole.
One of Musea's greatest achievements was the re-release of long-forgotten albums by groups such as Sandrose, Pulsar, Arachnoid or Acyntia, which belong to the milestones of French progressive rock history.
Since the size of the CD box did not allow for the same design possibilities as the vinyl albums, the label founders, together with a meanwhile expanded staff, decided to create elaborate booklets with a wealth of information, texts and pictures of the respective artists.
Musea then later offered the band to upgrade the original master tapes to a similarly high sound standard as the Japanese edition.
But the system also worked in the opposite direction: Musea could acquire licences from foreign companies in order to be able to publish them in Europe.
