[Welcome to Hammerjacks There are music venues, and then there are institutions, the kinds of places whose lore and legacy live on long after their doors have closed. New York had CBGB. LA had the Whisky A Go Go. Baltimore had Hammerjacks. Opened in 1977, Hammerjacks was synonymous with rock & roll in Baltimore for two glorious, debaucherous decades, playing host over the years to everyone from Guns N’ Roses and Ozzy Osbourne to Iggy Pop and the Ramones. Joan Jett shot the video for “I Love Rock ‘n Roll” there. Iron Maiden featured the club on the cover of its 1986 album Somewhere In Time. John Waters filmed crucial scenes for his cult classic Serial Mom inside. Belly up to the bar on any given night and you might have spotted members of Poison, Def Leppard, or Journey hanging out after nearby arena shows. “Hammerjacks,” the Baltimore Sun declared in no uncertain terms, “defined the Baltimore popular music scene.”]
