The Demosplash demoparty in Pittsburgh, PA has been announced — Nov. 4–5, 2016. Be there! Demosplash is a combination retrocomputing festival and computer-art competition. I went last year and thoroughly enjoyed it. The organizers will be posting more at demosplash.org soon.
Ars Technica has a great article on the history of the demoscene, particularly on the Amiga. I found it on pouet – check it out! Part Eight: The demo scene
