I found the music interesting and somewhat emotional, and thought it would make a nice sparse soundtrack piece. Sounds similar to serial music, related to Schoenberg who he mentioned. I'm only slightly familiar with this music, but it reminds me of some pieces by Babbitt. Here's a sample: http://www.npr.org/2006/05/10/5396502/a-difficult-composer-milton-babbitt-at-90. Definitely not ugly. If you're going to compare this "perfect sonar ping" to music at all, it seems like it might be worth doing a more serious comparison to previous composers who worked towards a similar goal.

I thought we had this already... http://idlewords.com/2007/04/the_alameda-weehawken_burrito_tunnel.htm
