Calhoun Conquer reminded me a bit of Mekong Delta -- they played thrash metal with progressive overtones, though they weren't quite as complex as MD, nor did they have the classical influences. Two of the members are listed as "percussion and drumcomputer", so I guess they had no real drummer, though I never would have been able to tell the difference. Lost In Oneself is a unique and interesting album, but apparently band never recorded again.
