Here's a big ol' collection of high-quality drums that were released for free on Music Radar. I took my favorites and compiled them into a big ol' PCMSynth preset for anyone in need of some great real drum samples!
More metal-banging goodness, and not in a Def Leppard kinda way. No, for fans of old Depeche Mode, Nine Inch Nails, Skinny Puppy, Ministry, Einsturzende Neubauten, Fad Gadget... or anyone who watched Max Headroom, the Mad Max movies, or the first two Terminator flicks... you know who you are.
Factory percussion, recorded at a recycling factory. If you liked Einsturzende Neubauten, or the music for the first two Terminator movies, or you wanted a few items for that certain post-apocalyptic sound, this is for you.
Just a regular 1 liter plastic bottle (≈ 33.81 oz). I noticed that when you gently tap on the side of the bottle, it gives off a pleasant low-pitched tone, almost like some kind of a bass drum, which is why I thought it could be used as a low-key percussive element in your Caustic creations. Alternatively, you could mangle it beyond recognition by time-stretching, bitcrushing and/or saturating it and filtering it through a multitude of other effects.
I thought something like this could be used as a slightly more exotic shaker-like percussive instrument. All the samples were recorded with my S3's built-in mic, so the audio quality may leave something to be desired. Blackcurrant flavor, in case you were wondering :)
