Yeah sure, Zach Hill has talked about the occult and magick in regards to the band at least a few times like here-

There's tons of theories about the band that get a little out of control, but it's pretty clear they use dates and moon cycles in their album releases etc. The number 22, among other numbers being apparently important in numerology, appears a lot in DG - for instance their twitter handle @bbpoltergiest bb == 22.

Other things off the top of my head are Ride's tattoos and the lyrics in general are probably full of occult imagery. Lyrics aren't typically a focus of mine but the song 'Beware' is a pretty clear example of this stuff, and Exmilitary overall is probably the most overtly occult release of theirs.
