I was weak and easily led.

In 1978, after enduring four or five years of wretched music made by men with long hair and beards and tendencies toward eonic guitar solos, I suddenly discovered that the only music worth hearing was made by clean-shaven men of limited musical proficiency. I embraced the Clash, the Pistols, the New York Dolls, the Ramones, and the Buzzcocks. I cut my hair and gave away some of my old records. I even threw out my copy of Jethro Tull's A Passion Play—which, now that I think about it, wasn't that bad an idea.

Then I woke up and remembered: I'd left the baby in the bathwater.

As a film title, Quantizing Hanson Hsu might not rank up there with Kissing Jessica Stein, but we work with what we have to work with. Hanson Hsu is the principal designer at Delta H Design, Inc., an acoustics and architecture firm based in Marina del Rey, California. Though he dabbles in some weird science, Hsu doesn't wear a white lab coat, literal or figurative. He's down-to-earth and personable, with a conversational style that evinces warm wit and a real love of music. At one point in our conversations, he exclaimed, "I get so much joy when things sound good."
