What's That Sound?

Last week's show included, what's that sound? And i felt like it was too much of a cliff hanger to not at least finish that up for you. The good news is that six people got it right. Next week we also won't be having a podcast because it's new year's. So you're going to have to hold on tight until the first podcast of 20 22,. when i think we'll do a year in hack's retrospective.
