Oh, Big Kenny. There are plenty of classic photos of Dylan and the Beatles, among others, singing with the mic directly in front of their mouth. Honestly, though, since I've only been recording "seriously" for a few years, I never paid that much attention to something like that. However, even now I'll sometimes see professional situations where the singer's even with the mic. I would think if it's not a harsh singer, with proper distance and a good popper, being even with the mic, or even a touch above it, since our sound goes down, would be best. But that's why I pose the question.
