The last of their 80's albums has been finally re-released as a 30th Anniversary Edition remastered and expanded with 4 bonus tracks.
3 versions of the album's single "Song In My Head" (12" Dance + Dub Mix and 7" Single Mix) and the B-Side "Riverine".
Available at CDBaby - like their other fantastic early 80's albums "Danseparc" and "Mystery Walk".
Both albums include as bonus tracks all the respective 12" versions and B-Sides. Which leaves only the 7" versions of "Black Stations / White Stations" and "Cooling the Medium" to be unreleased on CD - as far as I know.
