The new set from prog act DarWin, this might be even better than the first one. In fact, this is likely to make my "best of 2020" list. 

This album is an interesting and quite effective one. It gathers up instrumental and unplugged versions of several tracks from the previous two DarWin albums.

This is a concept album, but I'm not really clear on the concept. I do know that it opens and closes in the same place, after taking a ride across two CDs.
