I had all five of their albums at one time and this was always my favorite. Bought in late 1981 when I was living in Havre de Grace Maryland. A little different from their earlier abums this one has lots of synthesizers and horns although still playing their Reggae influenced rock. Of the eleven songs I would say that eight of them are killers. “Spirits In The Material World”,”Every Little Thing She Does Is Magic”(although overplayed is still a great song,love the piano),”Invisible Sun” and “Hungry For You(J’aurais Toujours Faim De Toi)” sung mostly in French are the first four songs on side one. The last four on side wo are also excellent, “One World(Not Three)”,”Omegaman”,”Secret Journey”,and “Darkness”. “Demolitian Man” was covered by Grace Jones and Manfred Man on his Somewhere In Africa album. Again this record and cover is not in the best shape but still plays OK.
