Here are some of my recent videos. All of my videos are improvizations. I usually just find a backing track, hit record and let what happens happen, even if the backing track is for an official song of someone's. I also tend to get rather lo-fi sound on the videos because I'm just using the damn cam's internal microphone, but it's not as bad as it used to be. The backing tracks, nonetheless, are rather muddy. Oh well.
