LP – Black VinylRepress. A Sphere in the Heart of Silence is a collaborative studio album by John Frusciante and 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. Frusciante notes, “It’s electronic music, but much more raw. We recorded this the same way we did Inside of Emptiness – with all the out-of-control qualities that I’ve been building toward with my style of playing and recording – but we used electronic instruments. There are some techno things with punk-rock-type screaming vocals. It’s only a seven-song album, but it’s, like thirty-eight minutes long.” Both of them perform vocals; John Frusciante sings lead vocals on Afterglow, Walls and My Life, and shares vocals with Josh Klinghoffer on Surrogate People. Josh Klinghoffer performs lead vocals on Communique, At Your Enemies and does the backing vocals for Walls. Tracklist: A1. Sphere [8:29]A2. The Afterglow [5:19]A3. Walls [6:19] B1.
