good to hear musicians dont have to travel anywhere really but sitting where they are already brought in by a venue played earlier why not spread the goodness.
yes there are artists who do lots of stuff for free one of our local festivals is entirely free..
but that is one exception in the larger landscape
I also note that in many of the festivals free and otherwise it is common practice for musicians to hide with each other behind fences and far away from the public. Perhaps so they will not play more than arranged but surely not so that they can communicate with the people. Many musicians play and then leave immediately.
For me the concept of the festival is to be centered on spreading the tradition one on one and networking and leveling experience.
I am of course glad for every moment a musician shares with the public. But this is not the attitude conveyed by the nature of the house concerts described here.
