Yep I've actually been listening to 衝動的の人 for a while now, he's one of my favorite arrangers. Pretty much have most of his work, plus similar circles: 鉄腕トカゲ探知機, モジャン棒, 空色作戦, dead space zombies. Recently I discovered that song I posted with mineko on vocals in some random MN-logic24 album and I just fell in love with the gritty instrumental and soft female vocals. Unfortunately most of MN-logic24's catalog doesn't sound like that and from what I've searched so far there isn't a circle that specifically makes that type of music - it's all spread out as one-off collabs. Though I guess I can count Kishida's earlier albums (picrel).
I'd appreciate more female vocal + 衝動的の人 arranged songs if you know more. Cheers anon.
