Allow Custom Radius in the Concerts page

Hello,

I think the Concerts page may benefit from an option to allow for custom radius when looking for concerts in a given location (both "Around Me" or a specific city.

Here's a bit of context:

However, my main point is that I should be able to set a custom filter on how much I'm willing to travel for a concert. In my scenario I am interested in concerts around me for about 50-60kms, but from a few tests I've run the radius filter is smaller because I can't see some concerts around me that I can see if I set the specific city. An alternative could be the possibility to set multiple locations to search concerts in, something that Songkick seems to do.

What do you think?
