Hey listeners. 20,000 Hertz started as a passion project nine years ago out of DeFacto Sound,

which is my sound design studio. Today, DeFacto still covers about 25% of the cost of this podcast.

So in a very real way, the work we do over at DeFacto Sound helps keep 20,000 Hertz going.

We just spent eight months rebuilding the DeFacto Sound website from the ground up,

and it's finally ready for you to check out. If you make videos, we'd love to collaborate. We've

worked with lots of 20,000 Hertz listeners over the years. And even if you don't need anything we do,

just visiting the site gives you a peek behind the curtain of this show and helps keep us high

in Google rankings. Take a look at defactosound.com.

Thanks.

There were titles like Nothing But Bass, Bass Boom Bottom, and It Came From Outer Base.

And while I never got into this scene myself, I knew a few people who were all about it.

For a few years, this bass tape subculture seemed huge, and then it just seemed to disappear. But I've always been curious, what was
