Some of the instrument has ties with Arizona's theatre organ history. The Flute Celeste is the Concert Flute from Phoenix's Fox Theatre.

Then, in October of 2002 fire destroyed much of what had been remodeled inside the Cathedral's sanctuary including the organ. Damage to the interior of the building totaled $5 million, but the structure remained intact.

The third remodeling of the church to take place in 20 years was completed in October 2005. The rededication included the 4/71 Shantz Great Cathedral Organ. Trinity Cathedral is blessed with an acoustic environment that truly supports great congreational singing and also enhances the musical experience of worship.

The organ, in a state of great neglect, was purchased by Adrian Phillips, Jr. and full restoration was begun in January 2002 under the supervision of noted theatre organist Lyn Larsen. All of the organ's components were painstakingly restored from the ground up by a crew of four full-time organ technicians who completed the task in 2006.

The Adrian Phillips Music Room measuring 178 feet long, 35 feet wide and 24 feet high at its apex, houses the organ. Currently comprised of 106 ranks it speaks from 7 chambers split between opposite ends of the room.

Representing a true revolution in organ design, the resulting instrument is able to successfully interpret the gamut of classical and symphonic repertoire, orchestral music, and theatre organ works. This remarkable instrument's design works because it makes sense musically. Like a chameleon, it can seamlessly switch among various styles, remainng faithful to each musical school of thought without the slightest compromise.

The building's design is expressly for the enjoyment of patrons, with the organ installed in four chambers at one end of the restaurant.. Forty-three foot ceilings provide unparalleled acoustics. The console is "presented" on an 8000 pound rotating hydraulic elevator. Many of the percussions (such as the xylophones, glockenspiels, drums, etc.) are installed in the dining room for greater audience appeal.

Over the years the organ suffered from some water damage after serveral fires in the Glendale Theatre. Al Davis, composer and teacher at the Phoenix College Music Department, heard of the existence of the WurliTzer. Al had always loved the theatre organ, so he went to work to see if it was possible to have the organ donated to Phoenix College. He knew the potential of the WurliTzer and set out to make it happen. After hours and hours of meetings he was finally able to get the donation from the Nace Organization and approval to install the organ in the school Auditorium.

Although the installation of the organ in the auditorium was begun in the '60's, it wasn't until 1975 that the Valley Of The Sun chapter became involved in the organ's restoration, replacing wind lines, wiring, and releathering. When Al Davis, then the chairman of the Music Department retired, the Music Department lost interest in the project and it was put on hold due to the inability to raise adequate funding to complete the restoration.

In 2004 Phoenix College faculty member Ellen Brown contacted the Valley Of The Sun Chapter with the hopes of returning the organ to playing condition. An agreement was negotiated with the Maricopa Community College District to restore and the use the WurliTzer. After nearly 30 years, the quest to make additions and restore the organ to concert condition has been realized.
