The Junto begins each year with the direction to "record the sound of ice cubes in a glass and make something with it" (or something like that, I forget!)
Some years ago I recorded my out-laws' glasses to make this project more convenient, as it often occurs around the hottest day of the year and they have air-conditioning that's quieter than mine.
I was really sloppy with the ice cubes as they sound better slurping around and even better when they fall on the carpet.
Those moments I've repitched to become snare and kick parts in the percussion.
