I think the future for musicians is in the internet, in sites like steemit and freelance jobs like the ones you can do in fiverr... I live from music just by posting my music on steemit.com and working as a freelancer on fiverr, it requires some patience and hard work on the beginning but you truly can make a good income from this sources and is way much better than going to a club and sing for 50 euros... As a freelancer you dont leave your house and your work the ours you want, you dont have to deal with all the bullshit you see in pubs, and you will build your experience and growth enough to make a good living... Thinks are about to change for musicians...
