Radiohead and the singing ghost

"Scotch mist - You thought that you saw something; you didn't; it was a track of the light, a phantasm, a spectre." Radiohead left their breakdancing backup dancers and sequined costumes stashed in the closet on New Year's Eve with an offering of "In Rainbows" tracks in their purest form, live from their Oxford studio. One of the highlights was getting to see Jonny Greenwood play the rare ondes Martenot close-up on "Jigsaw Falling Into Place." It's a fascinating device, electronic, invented in 1928 by French musician Maurice Martenot (ondes Martenot translates to "Martenot's waves"). It was inspired by its instrumental brother, the theremin (I saw this played at a rock show the other day). The ondes sounds like a singing ghost, or an angel. Get educated: Greenwood also plays the ondes on "How to Disappear Completely" and "Pyramid Song."
