Though kind of off topic and not really helping OP one bit, I got to comment on this.
For some reason the free play songs on their MySpace profile wouldn't play, but I found a few songs by them on Spotify, though there's only one 4 track EP and one various artists compilation, where they feature with 2 songs, available there.
Am listening through some of their songs in this very moment and I got to say it sounds really interesting and appealing to me, potentially even great, but think I will need more listening sessions to judge that.
My first impression, if I had to categorize the music genre wise, is that it has this distinct 90's/00's typical indie/noise rock sound and feeling to it, just without the use of dissonance, noisy parts and extensive use of distorted instruments, also sense a bit of a post hardcore vibe in it as well, but again in a non aggressive and kind of mellow way, and then all that put into a post and math rocky form, the latter genre reference though without it's typical use of abrasive rhythm structures.
Thinking about it the music actually fits pretty well into a post rock with vocals category, perhaps more so than any other genre influence I hear.
I like it.
And In every instance, thank you for making me aware of this band.
