Vangelis made some good records though, including one with Brian Odgers and Tony Oxley. Aphrodite's Child is pretty sweet as well.
New Age is a pretty wide range, much of it pretty interesting, and I would hardly put Laraaji or Schawkie Roth in the same category as the G.
Yanni and John Tesh are commercial lite music and that's another thing entirely. G is sorta in there and sorta not.
