It has taken me entirely too long to get around to covering a Petrels album, but London composer/multimedia artist Oliver Barrett's third opus turned out to be an ideal place to start.  Due to the complex and heavily processed nature of these pieces, the closest reference point is probably someone like Tim Hecker, yet Barrett's epic scope; talent for texture, dynamics, and melody; and passion for deep and unusual concepts place both Petrels and Mima in a category all their own.
