I want to suggest a Canadian space rock/psych act called Heavy Moon, a one-man project fronted by Jakob Rehlinger. He's involved in several projects, including Moonwood (I haven't heard his other projects so far), but this one I feel is clearly worthy of Prog Archives. The music has a bit of a Pink Floyd, Hawkwind, early Porcupine Tree feel to it, all instrumental. He plays all instruments here, including guitar, bass, drums, keyboards and synths. There's a huge back-catalog, but luckily they're numbered, so you never have to guess the chronological order of release. Here's how the music is like (there's a lot to choose from):

Discogs only has a partial discography listed, but Bandcamp has all the releases available, some of them available on solid format. Discogs mainly mentions the other acts that Jakob Rehlinger is involved in.

I really dig what I'm hearing here so far, and there's a ton more to dig into. I really think anyone who likes this type of instrumental space rock will sure dig this!
