The Captor of Gin was a standout at a previous Spirits in Black happy hour. Named after a Slayer song, the citrusy, herbal drink — a mix of genever, bourbon, orange aperitif and vermouth — was garnished with a piece of lemon peel cut into a cross. (Fritz Hahn/The Washington Post)

Some twists on classic cocktails take their names from bands (Napalm Death in the Afternoon, with a smoky house-made scorched absinthe) while other originals were inspired by songs. The Thing That Should Not Be, which takes its name from the Metallica tune, looked like a tropical concoction when you read the list of ingredients on the menu — aged rum, plum, lemon juice and sweet Velvet Falernum — but Owens added squid ink for a briny, savory taste and an unusual jet-black color.

The music and the theme are fun — as is seeing how many names of cocktails you “get” — but the excellence of the cocktails is what takes the night over the top.

The Darkest Sour is one of the most popular drinks at Spirits in Black. That’s the logo of local thrash band Darkest Hour on top: Bartender Patrick Owens shakes egg whites with bourbon, Cynar, Fernet Branca, port and blood orange juice to make a frothy base, and then sprays bitters through a homemade stencil to add the art. Unfortunately, someone stole the stencil at the last happy hour, so it won’t be made tonight. (Fritz Hahn/The Washington Post)
