Maryland Deathfest (often abbreviated to MDF) is an annual extreme music festival held in or near Baltimore, Maryland, USA. It has always occurred during Memorial Day weekend each year. The festival is the biggest of its kind in North America.
MDF is the idea of two extreme metal fans named Ryan and Evan. During the 10 years of festival history, MDF has featured over 350 bands from over 25 countries, many of which make their US debut at the festival. The festival is promoted with the slogan: "America's biggest metal party of the year."
Maryland Deathfest XI was held from Thursday, May 23 to Sunday, May 26, 2013. It was the first incarnation to feature the Baltimore Soundstage, a separate venue that catered primarily to punk and hardcore acts. It was also the last incarnation of the festival to be hosted at the former Sonar Compound, following its sale and rebranding as the Paparazzi Nightclub.
