Haugen's "Agape"

A correspondent writes me as follows, and I can't answer because I don't know the piece: "I'm writing because I would like to know your thoughts an a piece of music written by Marty Haugen. The piece is called AGAPE, and it's actually an entire concert piece in the form of a mass, but with many other things added. The piece is being performed at my university. I am trying to explain to the director why I am uncomfortable singing in the performance, but I'm not sure exactly how to put my words (besides the fact that it's 'musical' content is completely lacking in beauty.) If you are familiar with this I would appreciate your comments."

Anyone know this piece and have an opinion?
