Would be interesting to see this info on artists' pages like you can see this info on users' pages.

Example: 'X artist has played concerts in 52 countries, 82 cities, and 95 venues'.

Ideally this would include the option to see a full list of the countries/cities/venues in descending or ascending order, again like on users' pages - this would also show an artists' most visited venues, cities, and countries.
