For me, the glistening city of Nos Astra on Ilium is definitely one of the most iconic worlds in Mass Effect. So I made a track that describes the feeling I get when I am there. The track has a low end sub, occasionally mixed with a deep, mellow formant bass. Along with the ambient crowds, a chilling pad mixed with a distant piano plays to give atmosphere. Clear, crisp percussion and synths add more complexity to the track as it plays. Definitely friendly to vocalists if they care to sing over it.
