Heavy metal and beer is a marriage that has blended together hand-in-hand throughout the life of the genre, from Metallica in their early days having alcohol-fueled alter egos dubbed “Alcoholica” through the hundreds of bands that have shared their love for wicked brews in song. This weekend, over a dozen bands — including headlining veterans Possessed and Carcass and new-school greats such as rising melodic metal stars Spirit Adrift and power-violence masters Nails — descend upon The Observatory, with breweries such as Inglewood’s Three Weavers and San Diego’s Societe sharing plenty of pours to ensure a properly fueled mosh pit. The floor may get messy and sticky, but the beer will taste good and the opportunities for drunken headbanging will be plentiful.

Decibel Metal & Beer Fest takes place on Friday, December 13 and Saturday, December 14 at the Observatory.
