1. No, I didn't, but it's on my to-buy list. Problem?
2. I like to think my mixes are pretty decent, but I'm honest enough with myself to know I'm FAR from professional. I took a look at the list of bands he's worked with and nearly none of them jumped out at me. I don't listen to much metally metal anymore, and there's even fewer metal engineers I give a damn about enough to follow. The few that I do follow pretty much hang around on this forum or are discussed here frequently.
Don't turn this topic into some sort of witch hunt dude.
