Forest of Equilibrium is the debut album of the British doom metal band Cathedral, released in 1991 on Earache Records. It is considered a classic of its genre, doom metal. In 2009, Earache Records reissued the album along with four "bonus" songs that comprise the long out-of-print 1992 Soul Sacrifice EP. This deluxe digipak reissue also includes a poster of Dave Patchett's cover art and a new 40-minute documentary entitled "Return to the Forest" on DVD.
