Just going to sneak in a banger right before the end of the year. Yeah, the production could be better, but this scratches the itch for music I’ve been missing since ドレミ・ファ disbanded. ---

Apparently there’s a bunch of new releases incoming, and some of the songs have been made available on their official youtube channel (some of them feel like demos, REA had the whole ‘anormal’ mini-album released as a demo 6 months prior, so it checks out) From the 1st full album ‘リドゥルギア・アボミナティオニス’: [![](https://forum.jrockone.com/uploads/default/original/3X/5/4/541793d4da06c3efe23886bcb338281c27b5256b.jpeg "メメント - 冥鳴") ](https://www.youtube.com/watch?v=gK06JStp01U) [![](https://forum.jrockone.com/uploads/default/original/3X/9/1/911739b8d9235ff8d31b6609710646998d18b515.jpeg "メメント - くねくね") ](https://www.youtube.com/watch?v=pmkKqlrcFCg) [![](https://forum.jrockone.com/uploads/default/original/3X/0/7/072c57d9d8247f8835891f4124619abcd797c561.jpeg "メメント - 世界の終わり") ](https://www.youtube.com/watch?v=ML1ReK_uhJo) From the 2nd full album ‘摘出された御伽話の症例集’: [![](https://forum.jrockone.com/uploads/default/original/3X/0/b/0b1d794feaa58036d4cd45aba36538bb60446fad.jpeg "メメント - スリーピング・デッド・ガーデン") ](https://www.youtube.com/watch?v=bHe61LNub_4) [![](https://forum.jrockone.com/uploads/default/original/3X/9/1/91512e150acd88b52b93b27faefd5d74c848f3ed.jpeg "メメント - ストロベリー・ショートケーキ・シンドローム") ](https://www.youtube.com/watch?v=FKxCLa7C8TA) From the Concept Single ‘████████’: [![](https://forum.jrockone.com/uploads/default/original/3X/4/4/44c13c2fd680b624ea93e8b0f0cc558d2aa8b4ce.jpeg "メメント - あの日、殺したうさぎの事") ](https://www.youtube.com/watch?v=MMdia5nPfmY) From the 2nd mini album ‘Anormal 2’: [![](https://forum.jrockone.com/uploads/default/original/3X/c/0/c0a8c7a20623b3c847d1959b3218b439cd3740bf.jpeg "メメント - 死んだ女と見なかった最終回") ](https://www.youtube.com/watch?v=wDqH0NAsL-E) There’s some REALLY GOOD STUFF here, but damn this band could use an actual vocalist. Still, super exciting! ---
