One Day Remains: Pretty strong debut, love Open Your Eyes, Metalingus, and Broken Wings. Good production and all around a good album.
Blackbird: GREAT album, definitely where they really found their identity if you ask me. Great songwriting and I find myself singing the songs to myself at work all the time lol. First 3 songs are standouts and yes, the title track is an absolute masterpiece.
AB III: Haven't listened to this one as much, maybe because it hasn't 'clicked' yet. However, I do love Slip To The Void, Ghost Of Days Gone By and Wonderful Life.
None of them have topped Fortress for me though. But they're all good
