I'm not too familiar with Edge of Sanity, so I'll give them a listen.
Check out Crimson, it's one 40 minute song/album. If you like Opeth (as I assume you do), there's a 90% chance you'll dig EoS too

I tried getting anything by EoS, but failed. I found a few songs, but couldn't get anything close to a complete album.
