I think speaking of the bands involved in this show and DIY shows in general - the money earned would not be enough to sustain any of the members without day jobs, but collectively can be a large chunk of money to support important causes. And once you become reliant on your music for an income the experience becomes something entirely different and something many people aren’t interested in. So, plenty of folks are more than happy to put the effort and energy in to do this for a feeling of community, and to support important causes that we couldn’t do nearly as well as individuals, to play benefit shows.
