Dream Theater - I&W, Awake, FII
Exodus - Shovel Headed Killing Machine, Exhibit A, Exhibit B
Grimes - Geidi Prime, Halfaxa, Visions
Death - Individual Thought Patterns, Symbolic, The Sound of Perseverance
Baroness - Red Album, Blue Record, Yellow & Green
Between the Buried and Me - Colors, The Great Misdirect, Parallax 2: Future Sequence
That's all I got off the top of my head for now. Dream Theater was tough, because their last two are both in my top 5, with DT12 being ahead of Awake, but BC&SL is mid tier, but then again so is FII so it kind of splits evenly, but Images & Words is still no.1 so I give this trio the edge.
