Lou Reed, Metal Machine Music (CD)

The obvious thing that I notice on listening to Metal Machine Music is how much high-frequency overtone content is in guitar feedback. When modern bands like Robedoor and Skullflower exploit this palette, they record it so primitively that the high frequency overtones get lost. The excellent (uncredited) recording here (and fine re-mastering by Bob Ludwig, who the liner notes show as having mastered the original vinyl) reveals all of the beautiful harmonic detail. This reissue has nice packaging and a long essay in the liner notes too.
