Awsome Music

Firstly i would like to say that both the virtual and physical games are pretty awesome, but some of the music really stands out. I'm specifically interested in MenuTheme and Menu2: http://www.shadowera.com/music/. Can anyone tell me who composed them and if they have any albums with similar music in? And does anybody know of any other artists that compose similar music?
Thanks!!!

I know Mathazzar did some of the music in the game, not sure if he did the intro: https://soundcloud.com/mathazzar
