A community for any kind of ambient or ambient-related music.
This is an all-timer. Rain Temple, also by 2814, is another of my favorites. If you don't mind something a little more psybient that builds up, Hydroponics Garden by Carbon Based Lifeforms is another great album. Really anything by them, I'm a big fan, although my favorite album of theirs is Derelicts.
For ambient stuff similar to 2814, I really like Subaeris, albums like The City in Rain and New Tokyo Blue Mood
Birth of a New Day is one of the greatest of all time for its genre and sound but fortunately the artists involved in making it also made lots of other albums. I believe the artist 2814 is collaboration between HKE and Telepath. There is a lot more from both of them
These are some of my favorites:
Room 2814 - 2814
Lost Fragments - 2814
Rain Temple - 2814
HK - HKE
This - Hong Kong Express
Hong Kong Express - Hong Kong Express
Building a Better World - 猫 シ Corp. & t e l e p a t h テレパシー能力者
愛慕 ／ 悲哀 - HKE and t e l e p a t h
Gateway アセンション - HKE / t e l e p a t h テレパシー能力者
一緒に別の夜 - t e l e p a t h テレパシー能力者
I could keep going but it would be easier for you to just check the discographies of any of the artists mentioned. Check the discographies of any artist they collab with too
