Info from Wikipedia
The I-Beam was a former popular nightclub and live music venue active from 1977 to 1994, and located in the Park Masonic Hall building on the second floor at 1748 Haight Street in the Haight-Ashbury neighborhood of San Francisco.
After the I-Beam closed, the building (originally the Park Masonic Hall building), remained vacant and boarded up for 10 years until 2004. It was torn down and a modern apartment house with retail shops at street level was constructed on the site.
