As with Fear Factory's DIGIMORTAL, the upcoming SUPERCHARGER release from Machine Head will also be available in digipak format, AND both versions of the cd will be released simultaneously. So what is going to be so special about this digi release besides than the packaging? Right now the word is four extra tracks. They look to be shaping up as follows: "Hole In The Sky" (Black Sabbath cover), "Ten Fold" (b-side), "Rat Race" (b-side), and a 4th track that has yet to be determined.
