Trilogy is the third studio album by the English progressive rock band Emerson, Lake & Palmer, released in July 1972 on Island Records. Trilogy increased ELP's worldwide popularity, and included "Hoedown", an arrangement of the Aaron Copland composition, which was one of their most popular songs when performing live. Lake had said this was his favourite ELP record.
Essential: a masterpiece of progressive rock music
One thing is quite certain: ou can love this album to death or loathe it with every fiber of your being, but you can’t really ignore it. From the gorgeusly disturbing gatefold sleeve, displaying a masterpiece of Gothic artwork by Swiss cult artist R.H. Giger (of “Alien” fame), down to the unabashed self-indulgence of its musical content, “Brain Salad Surgery” is a compendium of everything progressive rock is all about, the good, the bad and the ugly. It is loud, metallic, and harsh, undeniably bombastic, though it can also be melodic and soothing – a true rollercoaster ride of an album, swinging from the beautiful, English choirboy vocals of “Jerusalem” (with wonderful lyrics courtesy of one Mr William Blake) to the all-out progressive orgy that is “Karn Evil 9”.
