The Buffalo Philharmonic Orchestra and Chorus in Kleinhans Music Hall, Buffalo, NY.
I found this nice image of the entire orchestra in action — they were performing Mahler’s Symphony No. 2 (the “Resurrection” Symphony) in 2001, so there’s the whole band on the stage at once. Kleinhans is an amazing concert hall, and the site linked by the image — the home page of Scott Parkinson, the BPO’s principal trombone player — has a nice gallery of Kleinhans-related images. Check out this one, an architectural model of the hall, with roof removed so that both concert venues — the main hall and the smaller Mary Seaton Room, used for chamber music recitals and the like — can be seen.
