The Song:"Percussions" is one of Beck's Planned Obsolescence DJ mixes. It was posted on beck.com, with a note from Beck saying that this was "an exercise in reduction, this mix contains only voice and percussion, inspired by recordings in which the song has been stripped to it's skeletal form."
Beck, as far as I noticed, never included a tracklist for this mix. Some of the songs and artists I recognized are:
Caetano Veloso "Tudo Tudo Tudo"
Joni Mitchell "Dreamland"
Beat Happening "Gravedigger Blues"
The Clipse "Grindin'"
Son House "John The Revelator"
Serge Gainsbourg
Nick Cave and the Bad Seeds "Black Betty"
