It's funny though... I read this article right before going to track in an SSL room for a project that was going to a somewhat more 'old school' engineer for mixing. I tracked everything super conservatively, probably not much in the sessions peaking more than about -10 or -12db. I talked to the mix engineer on the phone a while after and he had a totally different opinion... said I recorded everything too low and he struggled mixing it because he wanted more character from the analog gear... said I should have pushed the preamps hotter etc. Talking to him didn't really make me change my approach but it's interesting how everyone looks at this stuff differently.
