We had once an awesome unknown band from Belgium coming to play in our local club. I was the only person that came to the concert. For an hour they didn't start to wait for more listeners and they invited me to their table. No one showed up so they played for me and my brother whom I have summoned in the meantime. The best concert I have ever attended.

The band was L.T.D.M.S. (https://thomasturine.com/bands/ltdms/)
