I never taped from front row, but close to. From my own experience, clubs often mix in mono. That means you'll get a poor balance if taping from front row or close to a stack. Arenas often mix in stereo.
In most situations, I wouldn't tape from front row. Sound tend to get better if you can move a few rows back until you reach a point where you lose clarity and definition. Depending on what kind of act you're taping, you might get barely audible vocals when taping front row.
But pulling a good sounding tape relies on soooo many factors : your taping spot, your mics, venue PA and speakers setup, sound guy, high vs low ceiling, concrete vs brick walls, ...
You were talking about Rammstein I think ?
Well, that must be an arena gig. I'd suggest you to get a seat in the tier (if available), near to a speaker and to point a pair of cardioid mics right at it.
Edit: oh, and always try to mount your mics as high as possible. Shirt/chin level is not high enough. You could do better.
