Dün (…from their Wiki entry) was a French progressive rock band, active from 1978 to 1981, during which they played shows with Magma, Art Zoyd, Etron Fou Leloublan… In 1981, they recorded an album, Eros, that apparently never secured proper distribution, and as a result is quite rare. The French label Soleil reissued the Eros album, which included the four tracks from the original LP plus four bonus tracks, three of which are early demo versions of the tracks on the original release.
…That Soleil Atreides reissue has been re-reissued, remastered… here’s some samples: http://soundcloud.com/udi-koomran/sets/d-n-eros
aaand… aha, here’s where to get the album http://www.waysidemusic.com/Music-Products/D%C3%BCn—Eros-%28expandedremastered%29__Soleil-spc-Zeuhl-spc-33.aspx
“This is NOT a repress of the CD from 2000 but a new and completely reworked edition. Udi Koomran has done a brand new transfer from the 1981 tapes and he did a (brilliant!) new mastering which brings a new light onto Dun’s gorgeous album. A new bonus track has also been added (all of the bonus tracks from 2000 are still included) : a 1979 studio rehearsal of “Arrakis”. This is THE definitive edition of this all-time French classic!”
