[ ] Individual artists' recording spans

When you look at a band you get to see the earliest and last recording date, and a "lifespan" for that band.

It would be interesting to see the same when you click on an individual artist. Hence, for example, Miles Davis:

... who appears to have albums released between 1945 and 2011. But from the recording dates, his career was obviously shorter than that.
