You nailed it, brother. That’s exactly how I feel about it as well.
The Worn track on my EP, that one has field recordings from my footsteps on wooden stairs in a forest. There was this morning when the sun rose over a clear blue skie, and the first snow had just settled. I went out for a walk and rushed back home, family’s all like “He’s finally lost it, we’re calling the medics now”, grabbed my Deluge and went back to the woods to record my steps. As inconvenient as the Deluge is for that kind of spontaneous stuff, the results and the immedicacy in which you can apply them, is worth it.
But yes, that feeling, “I have to record this sound”, because it reminds you of something.
