Amok by Atoms for Peace- its got Thom Yorke, Flea, etc. and is amazing. Also Radiohead generally, especially In Rainbows for me. I love Phantogram especially Eyelid Movies, it calms me personally but idk if I'd call it decompression music, its a bit chillsteppy though if you're into that. Odesza. Most Grizzly Bear albums especially Yellow House. If you can dig jazz fusion I absolutely love Snarky Puppy for relaxing. What are yours?
