I do this kind of work. Right now I am in the process of doing a split release with a friend, and I’m just waiting on the artwork to do it official.
I don’t know that I am like the artists you listed, I have a lot of influence from straight up drone like Sunn O)) and Earth and more modern people like Tim Hecker, but I listen to all those artists you listed and love them.
I love to make this kind of music outside, especially in a park. Theres a park by me that is always empty, has a gazebo with outlets, and I literally go there with my Analog Keys and headphones and just jam for hours looking at nature. Really great experience for writing ambient drone stuff.
