It's a shame that quite a few of those projects never (officially) saw the light of day. There's so much stuff I'd absolutely kill for to have a high quality/official release.
Forever a shame that 'The Twelve Dreams of the Sun' has (officially) been gathering dust in the archives when it probably has the most interest arrangements of most of the tracks.
I understand that it's a matter of seeing what is worth releasing on a per basis*, but it's still a shame that quite a bit has been promised as receiving a release in the future, but for a deafening silence to end up taking their place.
The one thing that I absolutely love, and wish they'd do more often, was that absolutely random drop of 'Popcorn' for seemingly no reason whatsoever earlier this year.
Drop older singles this way, drop Travelator Part 1 and 3, drop C'est La Vie Part 2, just please... Do this more often! ;_;
*Not seeing the Dead Sea concert ever see the light of day, especially not considering everything that's currently going on over there these days.
Still that one concert where I am genuinely curious what the team was thinking when picking Israel for a concert, but that's a different matter altogether.
