A decade ago, Richard Spotts, an organist from Doylestown, started a very special journey: to perform the entire “L’Orgue mystique” by Charles Tournemire (1870–1939) — a fifteen-hour, two hundred fifty-three movement work that is rarely heard in its entirety. This journey took Richard across the United States and Canada, where he performed portions of “L’Orgue mystique” at numerous notable colleges, cathedrals, parishes, and other religious institutions.
