MᴀʀsCᴀᴛ "An Unexpected Memory" is just lovely. In spite of it being presented as a collection of unreleased tracks, it wouldn't be fair to call or regard the new NINGEN release as a collection of outtakes/scrapped pieces. These are all solid tracks, which slowly reveal NINGEN's focused, yet not limited, range of production; essentially, the worth of his talent. Could easily work as a loose introduction to his music.
(Disclosure: I have collaborated with NINGEN in the past, and he is a fwend of mine.)
Favorite track: Snowdin.
