To get exposure, I think its much easier today in many ways. CDs can be produced at low cost. You tube clips etc. at the expense of a small bit of time. Open mikes develop experience. You can listen to past masters on the net, get words/ tunes/ dances etc from the best, even do a degree in folk music where you can network with like minded performers. Owning a PA and a car costs less than it did. The main 3 week long festivals are in robust health. Some festivals have extended to the Thursday and Monday. If you want it, and have the talent, it can be done.
