I prefer Andy Wallace's mix overall to Northfield. Northfield wasn't bad, but he didn't handle the bass guitar's full register very well, so even when JM was cranked he would disappear in the upper range.
I still don't think ADTOE has the greatest mix or production though. It doesn't have any character to me. Not that that's necessarily a bad thing, it just makes it a bit plain, and I like DT to have more.
I would love to hear Kevin Shirley mix a new DT album. He handled all of DT's best and most distinctive sounding albums. He has been a bit too guitar heavy and keyboard light in the past, although I think that may have had as much to do with MP as anything else. But I want another DT album that sounds as good as SDOIT.
