I may be wrong, but it seems that the original release and the re-release are listed as separate albums. Look:
Atabal-Yémal
(Studio Album, 1979)
Tracks
Side A
1. Cascada (6:35)
2. Hecho de Horas (4:58)
3. Las Olas (Virginia Woolf) (7:27)
Side B
1. Atabal-Yémal (11:08)
2. Anhelos (3:30)
3. Presencias y Ausencias (9:36)
Ĺtabal-Yémal
(Studio Album, 1998)
Tracks
1. Cascada (6:31)
2. Hecho de horas (5:00)
3. Las olas (Virginia Woolf) (7:27)
4. Atabal-Yémal (10:09)
5. Anhelos (3:32)
6. Presencias y ausencias (9:31)
Bonus tracks on cd release:
7. KTR (3:09)
8. Un nuevo encuentro (10:35)
9. Arbol de la vida (10:08)
I noticed the (slight?) difference in tracks lengths, yet it still seems to me as re-issue of the original album. If it really is, one of the entries (the second one) should be deleted, the reviews should be transfered into the list of reviews of the original album.
Also pay attention to the difference of the initial letter of albums -- one with regular "A", the second is with diacriticised one. Don't know which one is right.
Once again, my apologies in case I'm mistaken and these two are totally different albums.
