Well, it all depends what you mean by … (tease, tease) … "scene", doesn't it?

If you are primarily a listener, then you could start by making a list of your favourite performers, and Google them, to find out if any are playing in your area anytime soon. Go to a concert, hang around the foyer and/or bar before and after the show, and particularly during the interval.   Pick up any leaflets on offer, and try to strike up a conversation about the music with anyone who looks friendly. If there is a "scene" in your area, that will probably lead you to it.

If you are a performer, finding a place to show off your talent may be a little harder. ("For many are called, but few are chosen." Matthew, 22.14.) In the USA, I suspect that a Google search coupling the name of your locality with the phrase "open mike" might be a helpful start.

On our side of the pond, we still have this archaic thing called the "folk club".   Some of them run small-scale concerts, where you can often hear good performers at reasonable prices. Young and unknown performers often complain that breaking into this circuit is difficult.

On the other hand there are clubs where you can have a five minute spot pretending to be a star - in exchange for spending two hours listening to other people pretending that they are stars.   Many aspiring performers claim that breaking out of this circuit is difficult.

Perhaps the best method might be to put a video of yourself on Youtube, and see if anyone emails you offering a gig. One can always hope!

Alternatively, you could join a Morris side, or a ceilidh band. Plenty of vocal and instrumental music-making goes on informally around the fringes of folk-dance events, and in my experience this is often more enjoyable than the packaged and managed fare you get served at clubs and festivals.

Wassail!
