Jelani Eddington demonstrated an art form of a bygone era on Oct. 23 at The Forum. Theater organs originally were played to accompany silent films, the single instrument replacing an entire pit orchestra. The theater organist had to have quick reflexes and a thorough knowledge of the instrument in order to match the mood, pace and personalities on screen, as well as sound effects. After performing a variety of popular and classical pieces revealing a variety of unusual sounds, Eddington demonstrated the craft of theater organist by accompanying a 1928 Laurel and Hardy silent flick, to the audience's pleasure.
