This was a special event hosted by Lincoln. They asked Beck to cover a song, and he brought 157 musicians to a circular stage and they all did David Bowie's "Sound And Vision." It was filmed with special cameras, and a highly interactive clip was put online.
Meanwhile, Beck took advantage of having so many musicians and an orchestra and did some other songs ("Paper Tiger" and "Where It's At"). He also did "I Am The Cosmos" solo. Think "Girl" was just with his own band, and not with all the musicians.
Tickets were given out online, however most who were there seem to have been special invites, etc.
The setlist also listed "God Only Knows," which was either to be the Beach Boys song, "Lord Only Knows," or a slot for anything is possible. Either way, it was skipped. Also "Sound And Vision" was performed once at the beginning and then twice more at the end.
