This is my new favourite video! I found it not long ago. It's a video of the Dragons doing improv solos during a show in a small club in what I think is 2011.
Dan is amazing at freestyling! And the drum, bass, and guitar solos are massively excellent as well.

For anyone who celebrates Christmas, you can hear part of God Rest Ye Merry, Gentlemen and Carol of the Bells. Carol of the Bells is my jam

Enjoy the video, and happy holidays to anyone who celebrates anything this time of year.
