The Ethereal Mirror is the second full-length album by British doom metal band Cathedral. Released in 1993, this album sees the band experiment a wider scale of sound than on their debut album Forest of Equilibrium. The songs are not as doom-laden and grinding as on the first album. Some of the songs contain the first hints of a musical change, which led to embracing stoner rock style on later records. It was re-issued in 2009 with a bonus disc and the DVD Ethereal Reflections.
