From the 2004/2005 six album series. It features Josh Klinghoffer and Omar Rodriguez-Lopez as guest musicians. The album genre is based around rock, with synthesizers playing only a minor role throughout. Inside of Emptiness is surely inspired by the raw production values of Lust for Life or White Light/White Heat. Considerably guitar-oriented it rocks hard up until the last track (a gentle rocker), without much polish As with the other albums in this series, Frusciante is wearing his influences on his sleeve but following his own vision, and it's quite interesting to track an artist's virtually unfiltered output over the course of a year or so. Inside of Emptiness won't win any awards for originality, but Frusciante deserves credit for maintaining a high level of quality with such a prodigious output.[info sheet from distr.]
