The bacteria Brettanomyces, aka bret, is used in the process of making geuze - a sour belgian beer which forms the basis for lambics (beer made with fruit). My first exposure to a true geuze was a few months ago and I loved it; there was a super tangy aspect, as well as a satisfying, meaty savor. It brought to mind some flavors that Burgundy sometimes shows. Brett, by the way, can be thought of as the fish sauce of winemaking. Nasty to think of it on its own, but in the right amount (it is a naturally occurring bacteria in many wineries) it adds a certain degree of umami to wine. Though I am not sure that brett is something which can be easily adjusted. I don't encounter brett too often in New World wines, though, on occasion I certainly have. Maybe as the 'American palate' evolves more people will demand different flavors, more akin to European wines, and it will be common practice to allow bret to flourish in vats and barrels? Not that this would necessarily be a good thing....
And about Kraftwerk, I learned that a few of their songs were featured in Master of the Flying Guillotine. The film also has a song from Neu! and Tangerine Dream. That right there is pretty cool.
