A friend of mine is really into this IDM/Ambient act and she recced me their albums a few months back. I enjoy Ilkae. They're mostly known for their first record, Pistachio Island (which is still my favorite record from them I've heard so far, but other albums such as Stained Glass Pinata and Light Industry are solid. Still need to hear their 2010's output that isn't their early material).
Aaron Munson sure crafts a sound of his own, some of the melodies he makes under Ilkae, he also has a lot of heavier, complex shit going on too that I enjoy. Ilkae used to be a duo until around 2004, Krystian Lubiszewski left the project, so since then Aaron has used Ilkae as a solo project They're definitely an obscure IDM act, but one worth your attention and time. If you want to see their early material before their first record Pistachio Island, check out 2013's Primer, featuring a lot of longer, awesome tracks throughout.
Here's Ilkae's Bandcamp, featuring their entire discography. Ilkae's around on streaming platforms too but not everything unfortunately, just most of the albums and some eps. https://ilkae.bandcamp.com/
I'll be surprised if someone else knows who they are haha. Also surprised by the fact that they have quite a few ratings on Rateyourmusic.
