I would love to see a feature that shows artist popularity by city or country. This would be incredibly useful when searching for local acts to perform. The criteria for determining popularity could include followers, number of events present on Shotgun, and event attendance. It would be great if this feature could be filtered globally, by country, city, or even by one or two genres. A similar feature was available on Resident Advisor, but it only covered the top 100, which wasn't ideal for local acts.
