There have been a handful of busking threads on here in recent years and there are, it seems, a number of members that make all or part of their livings as street musicians - myself included. Busking is not really a viable or sensible option at the present time:
i. If, like myself, you rely on hitching, lifts from friends or public transport to get around, then those are either unavailable or inadvisable;
ii. There are not many people on the streets;
iii. Many people will be feeling financially insecure and penny-pinching* as a result.
So, I googled "online busking" and came upon this site https://www.streetjelly.com/ , which enables the ‘busker’ to stream their music live from their home, whilst ‘passers by’ (who have subscribed as ‘Viewers’) drop in tokens that they have purchase from the site. One token holds a value of 16¢ (US) to the busker; the viewer pays from 20-32¢ per token, depending on the quantity they buy, so the website takes a cut of 20-50% on each token.
There might be other similar platforms out there, but this is the only one that my search brought up. The more tech-savvy could no-doubt set up something like this independently, cutting out the middle-man, so to speak. But that entails a lot of self-promotion (or ‘begging’ - which I am trying to avoid) to get your passers by. Streetjelly at least gets a lot of buskers in one place, so once someone is there, you have a chance of being found - I’m happy for them to take their cut for that service.
It certainly feels awkward trying to promote my own busking on The Session, whose membership consists of 240,000 musicians, perhaps 120,o00 of them better musicians than myself, and many of whom are trying to make their own livings out of music. So first of all, I appeal to all buskers or would-be buskers to check it out and consider using it (it would be nice to trad-bomb the site 😉 ). Secondly, I invite all those that find themselves in a position of financial security to have a look, buy tokens and give them to whoever warrants them.
If you’re looking for traditional music, you can search by genre in the ‘Live Preview’ tab: select ‘More Genres’, then you’ll find ‘Celtic’(*?%!) somewhere down the list…
*…by which I mean, of course, holding on tight to their own pennies, not pinching my pennies - although that could also happen, if someone is really desperate.
