The Tang family came to be, when I started studying fonts made for use in very small point sizes, like Bell Gothic. I studied the use of ink traps and went to town with them. Instead of just using them for their purpose: trapping ink to prevent the type getting blotted; I used them as a design feature.
With those features Tang works very well in both headline and text use. I use it as a house type, and I've already seen it in a beer and cider labels.
