Music like Guttural Secrete

Maryland Deathfest (often abbreviated to MDF) is an American extreme music festival held in or near Baltimore, Maryland during Memorial Day weekend each year. It is the biggest of its kind in North America.

Since 2015, the organizers of MDF have produced California Deathfest (Oakland 2015-2018, Los Angeles 2019-present), Quebec Deathfest (Montreal 2018-present), Netherlands Deathfest (Tilburg 2016-2019, Eindhoven 2020), and Scandinavia Deathfest (Stockholm 2019).

MDF was the idea of two extreme metal fans named Ryan and Evan. During the 17 years of festival history, MDF has featured over 600 bands from over 30 countries, many of which have made their US debut at the festival. The festival is promoted with the slogan: "America's biggest metal party of the year."
