TOUR OF CATHEDRAL OF OUR LADY OF THE ANGELS AND ORGAN RECITAL  Cathedral of Our Lady of the Angels
555 W. Temple Street
Los Angeles

Join with the American Institute of Organ Builders for a tour and series of lectures in the newly-completed Cathedral of Our Lady of the Angels. The prime focus of the tour will be "Opus 75"—the Cathedral's new 105 rank, 6019 pipe organ by Dobson Pipe Organ Builders (Lake City, Iowa). The tour also will feature a recital by the AES' "resident organist" Graham Blyth. (See Special Events page 34 for concert information.) Included in the series of lectures will be "The Cathedral Organ: The Truth Revealed," by Manuel Rosales, consultant to the Cathedral for the organ project; "Design Adventures: Collaboration with Architects," by Lynn Dobson, President, Dobson Pipe Organ Builders; "How to Hold Up 55 Tons of Organ," by Jon Thieszen, a member of the organ design team; "Entering the Tonal Unknown," by John Panning and Samuel Soria, Cathedral Organists (this will be a lecture and demonstration of the features of "Opus 75"). At noon, lunch will be provided in the Archdiocesan Conference Center, accompanied by a lecture, "Organ Structure: Preparing for the Big One!" John Seest will offer a look into the support of the Dobson Organ in the massive new concrete Cathedral and the attention given to the high earthquake design loads that make this a unique organ structure. Following the lunch and lecture, Graham Blyth will perform a recital on the Dobson Organ. To conclude the tour, Dennis Paoletti and John Prohs, acoustical consultants for the Cathedral, will discuss some of the unique design features and challenges they faced in realizing this massive and complex project.

Cost for the tour, including lunch, is $45 per person. Reservations are required and must be made at the Special Events Desk no later than 4:00 pm Sunday, October 6th. Convention attendees wanting to attend just the organ recital by Graham Blyth, but not the entire tour, are encouraged to check the poster in the Convention Center lobby for the starting time and additional details.
Attendance at the recital is free.
