Glenn's music has a knack at finding that area between where concious meets the unconcious, where form meets spirit levels in the human race, and speaks in a language that is both haunting and uplifting at the same time. I find it akin to sign language in that it is able to somehow communicate across all borders of difference and give a familiar feel that draws all in and comforts their souls, yet it seems to speak directly to you.
On the other hand, it's just good songwriting and I like it! Now who wants dessert?
