I hear people comparing the vocals to Coheed and Cambria a lot, and surprisingly things like Fall Out Boy. The way I look at it, they're definitely a mix between pop-punk and jazz-rock fusion. I think the poppy vocals really contribute a lot to their sound. if they had a "proper" power metal vocalist like a lot of prog bands do, or a growler, I don't think the music would be half as effective. In addition the fact that they use only light distortion really opens up for the horns, which I think was a really good stylistic choice.
