The genre has become almost--and perhaps unfairly--synonymous with the "New Age" movement and its focus on the spirit, metaphysical holism and the environment.
The genre itself is relatively young, getting its first real start in the 1960s and '70s with groups like Tangerine Dream, and that band's alumnus Klaus Schulze. Later groups and individuals that some might classify as New Age are Kitaro, Deuter, Mark Isham, Patrick O'Hearn, Clannad, Enya, Ray Lynch, Jean-Michel Jarre, and many others.
