Scientists from the 19th Century said the incoming hailstorm you can hear sounds from the clouds similar to lot of horse-wagons passing by on gravel road seconds before the storm arrives. That sound is the "postillion of God's whip" and can be heard from 13:50 in this recording.
Very rare sound! What was the size of the hailstones?
I love this recording SO much!! It perfectly captures the atmosphere you describe. I like to play nature soundscapes while I study, but often they're either so monotonous I get sleepy or they have all kinds of sudden spikes in sound that startle me from thinking. This has all that cheerful wakefulness of Spring and makes me feel like I'm sitting there with you.
Wow, beautiful rain recording, very relaxing and restful, I love this. Continue your good work with rain, maybe in spring 2014, in april month or may! I would like a very long rain recording, without loops in the rain, it's better to relax.
