Chris posted a picture in his Instagram story of a recording session for a project known as The Bell Witches. I did some digging, and it appears that Chris, Pat, and a few other musicians recorded some songs in 2015 that were never released.

Here is an album from that time:

Hope to see that music released someday! If anyone has more info about this project please post it here. Thanks!
