The act known as Scanner (aka Robin Rimbaud) maintains a good track record of posting new free music most months, and the first such MP3 of 2005 is a bit of one of his dance scores (Nemesis, written for the Random Dance ensemble), remixed by DJ Danger Mouse (mastermind of the headline-making Grey Album). Apparently Danger Mouse did this “long before” Grey Album. It’s a six-plus-minute piece, uncharacteristically melodic for Scanner, even romantic, along the lines of a Hollywood spygame score, and run through with percussive elements. Track here, more on Scanner at scannerdot.com. On the dance group’s website, randomdance.org, there are video clips of Nemesis being performed (navigate to “repertory”).
