1. Blackbird
2. Fortress
3. Wayward One
4. Fallout
5. Open Your Eyes
Naturally, there could have been a lot of substitutes on this list. Even though Open Your Eyes was not really as heavy or pseudo-prog-like as the later tracks (heck, I think it got compared to Higher, one of the most overplayed and, sometimes, maligned tracks amongst rock music, in the early days.), Open Your Eyes was the song that started it all for me which that thought can be the same for some AB fans. That or Metalingus.
