“Rock-and-Roll” or “Rock of Ages?” That’s the question being asked at a conference at the University of Northern Iowa. U-N-I Music Professor Marilou Kratzenstein says church musicians and lay people are discussing the changes in today’s church music. Such as the generation gap in worship styles and the differing expectations of worshipers.Kratzenstein says the views of those who play, and those who pray are often different. She says musicians who’re trained classically have different ideas than the people in the pews.She says they have participants from many denominations across the United States giving their opinions at the conference. She says some churches try to make services as entertaining as possible to try and lure people in. Others believe they should keep the traditional music.Kratzenstein believes they can come up with a solution to satisfy everyone.The conference, “Church Music 2000: Creating a New Vision” runs today through Saturday on the U-N-I campus in Cedar Falls.
