Although, of course, just because I can't compute DT12 containing no filler it doesn't mean no-one else can't
I love DT12. Some of the flaws are obvious, like the sound/mixing and mastering choices, but I feel like the songs come from a real place of them trying to make the best album for who they were around that particular time. If feels authentic, and, like Bosk says, it's one of the most consistent DT albums to date.
The songs, while also on the shorter side, have some pretty cool twists and turns on the songwriting aspect and not the technical side; and they definitely crafted these sections carefully to highlight the song, not just noodling for the sake of noodling. And the grooves, oh man, the grooves. As a bassist and drummer, the musical chemistry between MM and JM was a pleasant surprise back then, as it seemed they really worked together to fine tune those bass/drum parts
Also, it was released during a very bad/dark season of my life and it helped me go through it. For the first time I started paying attention to the lyrics and actually connecting with them, and those lyrics meant something special to me at that time (I was 18 back then).
