Uk birmingham canal between icc and aston, hotel with kitchen extractor fan mounted on roof of restaurant area. Noise on the cusp of being pitched from the cowl, superimposed on the fan motor pitch. H2 zoom front mic with wind shield, hand held, some wind noise.
I call this my flash boom. It's a sub plus a pitch shifted snare that i created on my track "a flash of light by the shore" use it to create dynamics on a hit or whatever you want. Give a shout out to stark for machines and have fun! :). - chris.
