Despite the last government's best efforts to kill informal live music, some hardy souls have been promoting House Concerts in the UK. Google "house concerts" +UK and you will find lots of them. The site that used to try and co-ordinate local listings seems to have ceased because it was too time consuming. There's actually lots of activity under the radar and there doesn't seem to be much overlap with the Folk Club scene so it is quite difficult to find local House Concerts but they are there in many areas of the country. One of the factors is that houses are usually relatively small over here so the promoters don't actually need to do much promotion to fill their capacity. Once they've got a bunch of regulars they hardly need to mention the events outside of their home crowd.
