Recorded with a sony ecm stereo microphone. It's hard to tell what this slam is, which makes it very versatile. I'm pretty sure, however, that it is in fact a distant car door slam.
There's a staircase where my college radio station is and this door slam gets me every time - metallic slam with big, booming reverb. I posted another version that is just the last booming part of the slam, it's called "door slam 1".
Skewer slam is a combination of my knife sharpening sounds and metallic impacts/wobblers (some not yet uploaded here!) to create a sesnsation of something big, intense and lethal coming towards whoever it either find offensive or is ambulatory. As a personal note; the distortion you hear is not because of clipping in the initial recording but because of the higher acoutistic resonance and limiters applied which will not sound like this when downloaded.
A fairly harsh and slightly clipped sample of foley artistry to create a heavy "shockwaving" impact. You may notice that this is the layering sound of skewer slam.
