Been watching some of the World Cup and hearing this strange drone all the way through the games. I guess it's some sort of plastic horn named, or based on, what's called a vuvuzela. Lots of discussion about banning them as too much interference, and some audio pros are calling out their favorite DAW plugins to filter out the sound. But I like the vuvuzelas much better than those damn boomsticks at baseball parks. Somehow the vuvuzela drone sound actually relaxes me, sort of like Indian sitar music (can't remember the drone instrument used with the tabla and sitar). Anyway, my son's friend came up with a concerto for vuvuzela... a very appropirate arrangement.... click on the graphic for a full blown display.
