Gearslutz user Shadowelectro has uploaded a free sample pack of found sounds and percussion samples recorded in NYC, San Francisco, and Vermont:
"Hey everyone, I created a sample pack consisting of found sounds and a lot of unique percussion hits that can enhance your productions in cool ways! The pack includes 80 samples recorded in NYC, San Francisco, and Vermont. Most of the sounds were recorded outside or in large spaces so you get some really great ambience going with the samples. I also included an Ableton Live Drum Rack Preset in there for all you Ableton users."
GO GET THEM!
