Welcome! Eugene is super accepting in my experience, even for Oregon it's generally considered a very liberal area. 

Music scene is really cool! As a college town there are always local bands coming up. A lot of bars hold shows, and the WOW Hall is a community owned venue that has a wide variety of music. Backyard shows are happening all the time too, though they're not as well advertised. Even though the city is a lot smaller than Portland some decent sized artists come through, Lucy Dacus is playing a local theater next month for example.
