Trilogy is the third studio album by English progressive rock band Emerson, Lake & Palmer, released in June 1972, by Island Records. The group had spent most of 1971 touring, which paused in September so they could record a new album at Advision Studios with Eddy Offord resuming his role as engineer. The album features "Hoedown", an arrangement of Aaron Copland's ballet composition which became a live favourite. The album was a commercial success, reaching No. 2 on the UK Albums Chart and No. 5 on the US Billboard 200. Lake's acoustic song, "From the Beginning", was released as a single in August 1972 and became the band's highest charting US single, reaching No. 39. Lake picked Trilogy as his favourite Emerson, Lake & Palmer album. Recording In September 1971, the band took a break in their touring promoting Tarkus (1971) and Pictures at an Exhibition (1971) to start work on a new studio album. They returned to Advision Studios in London, once again with Lake as producer and Eddy Offord as their engineer. In early 1972, New Musical Express falsely reported that the group were splitting up, causing the band to issue a statement. Keyboardist Keith Emerson had planned to do a solo album of jazz music, but the project was shelved and the band turned down a lucrative offer to write the score to a racing film entitled Fangio. The band recorded the album in October-November 1971 and January 1972. The album was particularly difficult for Lake to record, as he described the album as "such an accurate record." Palmer noted Trilogy had the most number of overdubs put down on an Emerson, Lake & Palmer album, owing to the "enormous detail" put into the arrangements of the songs. Emerson was pleased with the album after it was completed, noting its varied and difference in style compared to Tarkus. References to a quad version of this album appeared in 1974 Harrison or Schwann record and tape guides, listing Trilogy in the Quadraphonic 8-track tape cartridge format. Collectors report never seeing a Trilogy Q8 at retail, despite its having a catalogue number "Cotillion QT-9903". Songs Side one "The Endless Enigma" is a suite in three parts; the first section begins with the sound of a beating heart, an effect sometimes claimed to have been created by the Ludwig Speed King bass drum pedal of Palmer's Ludwig Octaplus kit.
