Mostly clips of the gigs that I visited, captured on my iPhone. For private reminiscence and to share with other people what I have enjoyed.
Of course all copyrights lie with the performing artists. When ads appear before the clips, these are there because the person or party who claimed copyright over the content allows ads. The proceeds do not go to me, but to the copyright holder.
Beside this I occasionally provide a peek underwater from one of my scuba dives.
