For me, layering metal music with bowed strings has worked more in theory than in practice. However, this track from the new Grayceon album, "Shellmounds," deserves some praise. The whimsical opening isn't just a teaser. It builds evenly, bringing in some jacked up riffs @ 1:49. I think the guitars could even a little louder, but there's still a great mix of energy and melody here.
