To build the range and palate of character that we needed for this collection, we transformed community park and green-way bridges into large-scale percussive instruments. We sought out 12 very special bridges in particular locations and sampled many different performances on them to elicit the right sorts of impacts that we were looking for. Each performed impact has 3 layers, 2 mono and 1 stereo, all with different perspectives due to mic placement. These sounds are highly dynamic, containing an artful blend of the locale they were captured in, and can add some very rich color to any explosion, impact, or crushing event in your editing mix. Go ahead and do your best (or worst)! These sounds can take a beating.
