Marin Škrgatić was a singer and bandleader of Croatian extraction whose work here should have been given a wider audience during the 1970s.  If you can believe it, according to Everland Music’s Bandcamp site, some of these songs were too progressive, if such a thing could ever exist.  The tracks are not only influenced by prog, but you can hear jazzy and operatic elements in some of the tracks.  This is an undisputed gem of Yu-Rock.
