Yup - In the Musica Sacra message boards, we now have a thread where the "music" of Marty Haugen is compared with the "music" of David Haas. Here's my favorite comment, so far...
When I hear Haugen's "Gather Us In" or "Sing Out, Earth and Skies," I feel like I should don a toga and join a band of Druids dancing around a big rock. The music sounds laughably primitive, pagan and cold. In fact, I even played the accompaniments sometimes for entertainment. When I hear Haas, I imagine Bing or Frank singing dramatic glissandos from the G to the D on the first verse of "We Will Rise Again." Amusements at best.
What I've noticed in the "melodies" of both of these guys is the frequent use of the following line-ending cadences:
suspended 2 to 3
suspended 4 to 5
suspended 4 to 3
I agree with Dave's comment above - "Amusements at best." (Amusingly funny, that is!)
