In 'Portraits' the recordings are not organised chronologically. It's more like a developmental process beginning with his early work in sythesizers and electronic orchestration (see 'Pulstar' and 'Alpha'). There are selections hinting at personal growth also such as the childlike sounds of 'Italian Song' and the innocence of 'La Petite Fille De La Mer'. Collaborative works with Jon Anderson, who could be called the voice of Vangelis come next, and then we are treated to the grand and epic orchestral pieces. Tracks such as 'I'll find my way home' and 'State of Independence' no longer hint at personal development, they speak directly to self discovery, spiritual quests and growth. These themes are also woven into 'Conquest of Paradise' and 'Chariots of Fire' and tell me that 'Hymn' and 'Antarctica' don't make you contemplative.
