HHH - Live Shows & Events Calendar

I'd love to see a way for HHH to share upcoming shows and events. Can anyone recommend a system?

A calendar of tagged events might be a good solution. For example, Beat Junkies are playing in San Francisco on Saturday, Oct 23. If all events appeared on a calendar I could easily refine by location to find upcoming events, such as this Beat Junkies show.

An example of such a system is yelp, where I can refine by price, neighborhood, hours, etc. to find relevant lists.

Can someone help me understand if this is possible and how to make it happen?

Thank you!
