I don't always do this, but I love cutting off after a sudden change in the piece. Like something that wasn't there the entire time is there for the last .5 secs to take the floor out of the listener. Sometimes something shrill for a last sting or so ducking low that it knocks the whole thing off. I HATE editing afterwards, but with tapes I have to make sure there's two symmetrical time slots, so when editing i often try to find a point of this to cut into.
Also love the Crass effect, where the track ends quietly for next track to be very loud before the quiet track even completely ends.
As long as it stops i'm fine. If it doesn't begin even better.
If the piece is longer than 10 mins and the ending gets your attention - it stinks.
https://kevindrumm.bandcamp.com/track/we-all-get-it-in-the-end I always already have dread whenever I put Imperial Distortion on, because by the time the very last minute of the double cd album goes on, I'm too in the zone and drowsed over the bed/couch. The minute by itself is probably not his harshest work, but as it's presented I can never forget the feeling of it, it's the only thing that truly gets hair in back of my neck to perk up every time.
