I just moved to a new city a few weeks ago and have started going to music shows weekly. Shared experience is a great way to connect with new people, not just enjoy something together with friends. I just met a new friend yesterday, and have had nice conversations and interactions with a number of other people that either turn into just a nice one-time experience or a potential friendship.

Sporting events and music shows are, I've found over the years, great things to go alone to. It might be a bit intimidating to start talking to a group of people, but approaching someone who's by themselves (or even a small group) can lead to a nice conversation or potentially something more lasting.
