John Frusciante & Josh Klinghoffer A Sphere in the Heart of Silence LP

Although John Frusciante is best known as a guitarist with the rock band Red Hot Chili Peppers, he also has an active solo career, having released 11 albums under his own name. His solo recordings include elements ranging from experimental rock and ambient music to New Wave and Electronica.

A Sphere in the Heart of Silence is a collaborative studio album by John Frusciante and future RHCP guitarist Josh Klinghoffer, released on November 23, 2004 on Record Collection. The fifth in a series of six releases Frusciante issued from June 2004 to February 2005, the album is composed mainly of electronica-based material.

John Frusciante calls Sphere in the Heart of Silence, his collaboration with Josh Klinghoffer, 'a record of electronic music,' but it's not nearly as 'electronic' as that statement makes it sound. It's really more an allusion to the fact that his other releases of this year have been mostly comprised of guitar, bass and drums, and that there is some programming, synth-work and overdubbing on this one... Some of these tracks were written around the time of Shadows Collide With People, and others were written for specific performances, so the album feels more like a series of experiments rather than a cohesive album. Still, you've got to give Frusciante credit, as this is his sixth release of 2004, and they've all had some strong moments.
