The lecture recital was given July 10, 1973. The Symphonie-Passion by Marcel Dupre was performed following a lecture on various factors that influenced the development of the organ symphony in France. In addition to the lecture recital, three other public recitals were performed, including solo compositions for the organ and three chamber works for organ and instruments. The first solo recital, including works of J. S. Bach, P. Hindemith, L. Sowerby, and L. Vierne, was performed on June 4, 1969. On April 17, 1970 the second solo recital was performed. Compositions by J. S. Bach, D. Buxtehude, M. Duprd, N. Dello Joio, S. Karg--Elert, and J. Langlais were included in the program. On January 25, 1971, a program of organ chamber works by N. Lockwood, D. Pinkham, and F. Martin, as well as solo works by F. Lizst, W. Latham, and Marcel Duprl, was performed. The four programs were recorded on magnetic tape and are filed with the written version of the lecture as a part of the dissertation.
