On his 18th birthday, writer/teacher Ryan Knighton was diagnosed with retinitis pigmentosa and told he would eventually go blind. It has taken 15 years, but now Ryan has less than 1% of his vision left in one eye, and is waiting for the last little bit to go -- As Ryan prepares for his own coming blindness, he heads to Germany to find an organ on the occasion of a note change - one note giving away to another -- in a song that the faithful know will not end until September 2639. The song is called As Slow As Possible. The organ is known the John Cage Project.
