Something like Fleshgod Apocalypse or Keep of Kalessin. Fast, clean. I don't know how else to describe the melody than that. You know what I mean. Like Krisiun's sound in the 90's (or maybe they're still around). Symphonic elements are okay as long as it's not what's driving the music, like Fleshgod. Something more mid-tempo like Septic Flesh is okay. Didn't like their last album as much though. I've been out of the "scene" for a long time so I can't reference any more bands.
