Now that's different, & very cool. It comes across as quite dry, but in a good way, because unlike most dry snares, it's also got some tone behind it. I applaud the untreated recording too, but I have to ask, how was it mic'd?
I really liked the high tuning. I think the lower tuning left a little something to be desired. I have heard that the innermost ply is the most important in drum sound. Maybe the brass dries the sound up a bit, but it sounds like a wood snare to my ears.
