Scanning five pages and saw that Rautavaara hasn't got mentioned yet. After decades of stylistic evolution, Rautavaara's mature style is marked by gently flowing, swirling melodic lines, never venturing too far from a focal point, but never repeating either. In this sense he reminds me of Mahler's "love music" like the famous adagietto.
Try his Symphony No.7 ("Angel of Light") and his Piano Concerto No.3 ("Gift of Dreams"). He is already quite well-known but I think he still deserves a bigger audience. Just avoid the opera Vincent.
