Just doing a little research, after listening to another Winterland show...
Winterland Ballroom - Wikipedia
The venue was opened on June 29, 1928, as the
New Dreamland Auditorium.
[2] It served as an
ice skating rink that could be converted into a seated entertainment venue. Sometime in the late 1930s the building's name was changed to
Winterland, and it successfully operated through the
Great Depression
The arena was located at the corner of Post Street and Steiner Street, it was converted to exclusive use as a
music venue in 1971 by concert promoter
Bill Graham
Winterland closed on New Year's Eve 1978 / New Year's Day 1979 with a concert by the
Grateful Dead,
New Riders of the Purple Sage, and
The Blues Brothers. The show lasted for over eight hours, with the Grateful Dead's performance—documented on DVD and CD as
The Closing of Winterland—lasting nearly six hours. After the show, the crowd was treated to a hot, buffet-style breakfast. The final show was simulcast on radio station
KSAN-FM and also broadcast live on the local
PBS TV station
KQED.

Winterland was eventually razed in 1985 and replaced by apartments.
