As the name would make you think, this disc is taken from a pair of 1975 shows. Tracks 1-8 were recorded like at Kiel Auditorium in St. Louis, MO on September 18, 1975. While tracks 9-10 were recorded at the Schaeffer Music Festival in New York, NY on August 29, 1975. Strangely, tracks 3 and 7 contain multiple songs on the same track.
