Castle Rat adjacent bands?

I am in love with Castle Rat. Only discovered them last week.

But I am not really educated on Metal. I know some classics. I love the first 6 masterpieces of Sabbath, I grew up to System of a Down and Metallica and I love King Gizzard's Petrodragonic Apocalpyse.

What else would you recommend to me that has similiar vibes? I love 'psychedelic' Metal sounds, but am open for anything.

Where else, besides Black Sabbath, drew Castle Rat inspiration from and are there adjacent bands?
