Picking out a single album from Deuter’s catalog as “essential” is nigh impossible. However, Earth Blue gets the nod because the CD illustrates that Deuter is as good at crafting ambient music as he is at his more typical New Age genre. Intermixing floating, serene electronic selections with more uptempo numbers featuring sparkling guitar melodies and lilting flute and recorder, this music, commissioned for the Autostadt Exhibition in Wolfsburg, Germany, is a revelation of the depth and breadth of this man’s superior talent.
