The San Francisco Symphony gave its first performance on Friday, December 8, 1911 in the Cort Theater at 64 Ellis Street. The Symphony stayed at the Cort Theater when it was renamed the Curran Theatre in 1918 (not to be confused with the present day Curran Theater at 445 Geary Street, which wasn't built until 1922). The Symphony then moved to the Tivoli Theater at 75 Eddy Street for the 1921–22 season, then moved to the newly constructed Curran Theater in 1922 and stayed until 1931, then back to the Tivoli Theater from 1931 to 1932. On November 11, 1932, the Symphony moved to the new War Memorial Opera House at 301 Van Ness Avenue, where most of their concerts were given until June 1980. The pops concerts were usually presented at the Civic Auditorium. The final concert in the opera house, a Beethoven program conducted by Leonard Slatkin, was in June 1980. The Orchestra now plays almost exclusively in Louise M. Davies Symphony Hall at Grove Street and Van Ness Avenue, which opened in September 1980 with a gala concert conducted by Edo de Waart, televised live on PBS and hosted by violinist/conductor Yehudi Menuhin. Davies Symphony Hall underwent extensive remodeling in the 1990s to correct a number of acoustical problems. The hall is also home to the second largest concert hall organ in North America, a Fratelli Ruffatti 5–147.
