Emerson, Lake & Palmer (ELP) were an English progressive rock group. In the 1970s, the band was extremely popular, selling over 30 million albums and headlining huge concerts.
The trio consisted of:

* Keith Emerson (originally from The Nice) keyboards
* Greg Lake (originally from King Crimson) guitars, bass guitar, vocals
* Carl Palmer (originally from Atomic Rooster) drums, percussion

After playing at a few of the same concerts, Emerson and Lake tried working together and found their styles to be not only compatible, but complementary. They wanted to be a keyboard/bass/drum band, and so searched out a drummer.

Jimi Hendrix was considering joining the group; the British press, after hearing about this, speculated that such a supergroup would have been called "Hendrix, Emerson, Lake & Palmer", or HELP. Before settling on Carl Palmer, they approached Mitch Mitchell of the Jimi Hendrix Experience; Mitchell was uninterested but passed the idea to Jimi Hendrix. Hendrix, tired of his band and wanting to try something different, expressed an interest in playing with the group. Due to scheduling conflicts such plans were not immediately realized, but the initial three planned on a jam session with Hendrix after their second concert at the Isle of Wight Festival (their debut being in Plymouth Guildhall a day or two earlier), with the possibility of him joining. Hendrix died shortly thereafter, so the three pressed on as Emerson, Lake and Palmer.

Their first four years were a creatively fertile period. Lake produced their first six albums, starting with Emerson, Lake and Palmer (1970), which contained the hit "Lucky Man". Their best known early performance had been a relatively modest show at the August 1970 Isle of Wight Festival, one of the last of the great Woodstock-era festivals. At the end of their set, Emerson and Lake lit two cannons either side of the stage.

Tarkus (1971) was their first successful concept album, described as a story about "reverse evolution". The March 1971 live recording (Newcastle, UK) of the band's interpretation of Modest Mussorgsky's Pictures at an Exhibition was issued as a low-priced record, the success of which contributed to the band's overall popularity. The 1972 album Trilogy contained ELP's best-selling single, the understated "From the Beginning".

In 1973, the band had garnered enough recognition to form their own record label, Manticore Records, and purchased an abandoned cinema as their own rehearsal hall. In late 1973 Brain Salad Surgery, with an eye-catching sleeve designed by H.R. Giger, was released and became the band's best-known studio album. The lyrics were partly written by Peter Sinfield, who was the lyricist for King Crimson's first four albums. The subsequent world tours were documented with a massive three-LP live recording, Welcome Back my Friends to the Show that Never Ends.

By April 1974, ELP were top of the bill during the California Jam Festival, pushing co-stars Deep Purple to second billing. ELP's California Jam performance was broadcast nationwide in the US and is often seen as the summit of the band's career.

The ELP sound was dominated by the Hammond organ and Moog synthesizer of the flamboyant Emerson. The band's compositions were heavily influenced by classical music in addition to jazz and ? at least in their early years ? hard rock. Many of their pieces are arrangements of, or contain quotations from, classical music, and they can be said to fit into the sub-genre of symphonic rock.

Onstage the band exhibited an unorthodox mix of virtuoso musicianship and over-the-top theatrical bombast. Their extravagant and often aggressive live shows received much criticism in this regard ? although in retrospect it was all rather small change compared to later rock spectacles: the theatrics were limited to a Persian carpet, a grand piano spinning end-over-end, a rotating percussion platform, and a Hammond organ being thrown around on stage to create feedback (it was the same organ every time, called the L100, that was repaired overnight for the next show). Emerson often used a knife given to him by Lemmy (who had roadied for Emerson's previous band, The Nice) to force the keys on the organ to stay down. Another unusual factor was that Emerson took a full Moog modular synthesizer (an enormous, complex, and touchy instrument under the best of conditions) on the road with him, which added greatly to a tour's complexity.
