2010. This could have gone in ATS perfectly, especially the whole When They Come For Me/I'll Be Gone (both fifth track on each album) would fit better with the story/concept album.
Structure gives it a unique new style that they haven't used very often. Hoping it continues on LPU XIII and LP 6.
As for my opinion, I love it. IBG was one of my favorites when LT came out, though it has become a little stale at this point. I can imagine this being performed as a major theatrical production that we will never get.
If this had Primo's instrumental with less electronic drums and kept the melody but with IBG's lyrics and regular drums, it could work on both ATS AND LT.
And I can tell what Primo was and became kind of was LP's baby since they began on it. Going from this in 2010 (or even earlier) and then reworking it to a whole new song over a whole year, bringing in Owen Pallet, and on top of that 2 remixes (one of which having Mike's rap part) in RECHARGED. Ironically enough, IBG gets no live time.
