They're not bad. I don't quite know how else to describe them, the guitar riffs are pretty expressive and lyrical in their own way, and at times it sounds more rock-ish than metal. Don't expect blast beats or crunchy br00tal guitar.
if you like Cynic-sounding metal, and don't mind other influences like some more fusion or world music stuff thrown in, you must get the first Gordian Knot album.
