I'm a fan of Electro/Industrial/Goth music, and frequently document the shows I attend, by way of my video camera.
At this point, I exclusively use a Panasonic DMC-ZS3. I carry up to 8 batteries for it, and 88 GB's of memory.
If it's dark, inspiring, or emotional, I might enjoy it.
Please don't ask me to send you copies of my original video files. If you want them, download them off youtube -- there are apps that will do that for you.
Support these artists. Attend shows, and buy their albums. You never know what kind of experience you'll have by getting out there and enjoying a good live performance.
