I was recording a thunderstorm. I have recorded all the Great Lakes, Niagara Falls, the Atlantic Ocean, a babbling brook, birds, bullfrogs, peepers, leaves falling, wind whistling, geese honking ... what's so odd about a thunderstorm? Actually, I recorded most of that stuff using a Roland VS-1680 with a battery pack and a camper's foldout table & AT825 microphone...now with the R-09, I keep it in a padded Promaster digital camera case on my belt and I'm ready to catch anything...recorded a train whizzing by at ~8 feet away...holy $&!t that had some low end. And yes, I record music also.
