Pelagos are a Finnish band and there are some former Circle members involved. That's almost all I know about the band.
So I didn't know what to expect when I started listening. The opener Code is an atmospheric tune with synth and leads you into the sonic world of Pelagos. My first thought is Tangerine Dream meets Pink Floyd meets... some prog rock.... Blackfield...
In a way they present a sound track to a move never been made. They have pleasant vocals lines combined with electronic sounds, repetitive sometimes, but surprising, too.
Still ambient, but with other ingredients is Aphrodite's Shore. The atmosphere is different, almost threatening. While Invisible has some folk-ish elements and reminds me slightly of Kaipa with moody vocals... But all this doesn't really fit, it might give you an idea what to expect, but at the end of the day you need to listen to Revolve!
