That's a great one. I own like 5 or 6 of their albums. I love them so much, and Tsumibukuro is a legend. Their Kancolle covers are also excellent.
Mirado
幻想風穴 ~ Loop Place is another favorite, because of the homage to Dirty Loops' "Hit Me" at 0:45
Truly the ultimate hype man. All of the jazz covers are great; for anyone else interested (as I'm sure you know this already) they also do orchestral stuff under the same banner which is good as well, but I feel like we get so many orchestral arraignments of songs that the jazz ones really stand out as being something unique and interesting. It all flows so well and has little flourishes like what you pointed out, I love every cover they put out.
