Sadly most American cities are driving cities. Downtown is really only alive for commerce during the week. On the weekends, people drive out to the mountains. It is definitely a "healthier" city so there is less of a bar scene and more of a stay home and smoke pot vibes.
The few live music theaters are just to the east along Colfax (~15 street) past the park and courthouse. There is also a fun strip on South Broadway just across from the Washington Park area. Just a shame because so few places in US are functionally walkable.
Aah, that does make sense. Well, who knows. Maybe I happen to be there again at some point in my life.
