German ambient band Maeror Tri explain their music:

We understand our sound as 'transcendental music' - a tool for the listener to open his mind, to sensitize his sense at the highest degree. We want to transmit a total openness, the bursting and overcoming of all mental barriers, the breaking out of the enforced subject "Tunnel-Reality" of modern society. Thus music can be a way to develop and evolve our minds.
