LUNA PARK is beautifully done but when I listen to it I get the feeling that I am listening to a soundtrack. The music seems to have been created for visuals that I am not seeing. It would be a perfect accompaniment for underwater footage of great whales, or the flight of wild geese, or a tour of the solar system. I don't mean this as a put down of the composition - in fact, quite the opposite. There is an art to music that is made to complement visual images without focusing attention on itself.
Music of this sort is generally classified by the music industry as "New Age". Most composers resent this and feel that it belittles their work, and associates it with new age crackpots and California hot tub spirituality. New Age music of the electronic variety generally relies on a number of elements that we hear clearly in LUNA PARK and in other types of "Ambient Space Music": extended consonant synth pads under sequenced arpeggios with a solo acoustic instrument or vocal (often in a neo-Celtic or "Faerie" style) designed to create an atmosphere of relaxation, inspiration or upliftment.
"Ambient music" is designed to surround (from the Latin "ambire" = to surround). It is not intended to lead the listener anywhere, it is simply supposed to envelop. For those who want the music they listen to to shake them up, stimulate, or challenge them in some way ambient, as Fred points out, is "bland".
