Conventions with Filk programming
Worldcon, aka the World Science Fiction Convention, is the annual international gathering of science fiction and fantasy fans, writers, artists, musicians and other creators. First held in New York City in 1939, Worldcon moves around the globe, held in a different city and organized by a different volunteer organization each year.
CoKoCon is a traditional sf/f con in Phoenix, AZ which will be held over the Labor Day weekend in 2018. The name reflects that it’s the CopperCon and ConKopelli Convention, sponsored by both CASFS and WesternSFA.
