Three showings: 7 p.m., 9 p.m., and 11 p.m.

The organ studio and CSU faculty artist Joel Bacon present the 13th annual Halloween Organ Extravaganza, with classic (and not-so-classic) works, including the famous Toccata and Fugue in D minor by Johann Sebastian Bach. Spooky sounds, combined with lighting and special effects, are sure to put you in the Halloween spirit! “Since it’s also the 50th anniversary of the organ, this Halloween we’re going to do something pretty special, and I’ve got some crazy ideas,” promises Dr. Bacon.
