Check out Austin Texas https://do512.com for inspiration of music/event trackers. Personally, I think a "Whitelabel"-able version of this, ready to be localized to a city/town, would be cool - especially if it generated custom calendar (iCal). I checked out potential alternatives, and really didn't seem much out there - especially that would be attractive/stylish to music fans.
Additionally, an "MVP" could be a single HTML page, which lists all the recurring events, grouped by week-dat on a week calendar. For example, if there's a venue which hosts a weekly jam session on Thursdays, you could add that once and it would always show up for the "What's happening Thursday?" area. Usually there are a bunch of recurring events in any town, so the calendar page quickly becomes a useful "what to do today/tomorrow" guide, with minimal effort.
