As I understand it, the drum walk is one of many exercises to help you experience how, because we are vision-entic, we have foregotten to be aware of the sensory input of our hearing, touch, smell, etcetera. Be excluding vision with a blindfold, you experience navigation with your other senses and learn that your awareness of the feeling of slope, the sound and feel of what is underfoot, the echo-non echo / sound-deadening qualities of close objects, the smell of certain flora and fauna as you near them, and such are always being offered by your senses if you open your awareness to them.

Dim light navigation, stalking, moving quietly, back-tracking, and things I am sure I have not yet discovered can all be materially aided by wider use of more of the clues offered by our senses.

I continue as a student of these practices.

Ah, ok. I believe I get it, and that sounds interesting. I would still suggest some sort of helmet though, in case you trip on something or walk into a branch.

Yeah, I seriously considered full body armor!

Part of the idea is to learn a different way to walk that eliminates almost all potential for tripping, stepping on dry crackly branches or leaves, etcetera. In the group I am learning from it is called "fox walking." I hope to be taught this technique in a week or so.

Another part of the idea is to learn to sense objects as you approach them, but from what I can see everybody walks into branches from time to time. The blindfold offers some eye protection and your relatively slow speed limits most potential injury. I do wear a substantial hat with a brim and crown that also limit potential injury, but I get your point.
