Epic, Opulent, Massive, Synthetic, Wall of Sound
You could compare Lush Atmospheres to Melodic Scapes, sans the melodies. These are tonal in nature and generally very full, thus the "wall of sound" description. This is what you might here at the final phase of a game or at a point of resolution. These Atmospheres are generally not negative sounding per se but may have some spooky elements. And again, these sounds could make great menu screen music.
