This is a live, unfiltered, acoustic recording from a recital performed by Dr. Jeremiah Martin on the 5-manual, 44-channel Ambassador Organ using an early version of the dry 80-stop Father Willis sample set from Silver Octopus.
Please keep in mind this is an unfinished instrument for which a detailed voicing has not been done. Creature noises and air handlers are evident in the recording, but hopefully the organ shines through all that.
