From the Milwaukee Journal-Sentinel, August 9, 2012:
Demolition of Sydney Hih, once a home for '70s counterculture and the alternative music scene of the '90s, is under way. It began Thursday and may take several days.
... In the basement was The Lost Dutchman Mine, a bar where folk music ruled for a while. Later, the space became the Golden Shaft, one of Milwaukee's first gay bars, and then a disco.
