The result was progressive rock's most flamboyant classical-rock synthesis: Emerson's assault on Hammond organ, piano, and Moog modular synthesizer — quoting Bartók, Copland, and Mussorgsky alongside knives driven into his keyboard — paired with Lake's melodic bass, ballads, and production sense and Palmer's virtuosic, percussive precision. Albums like Tarkus, Brain Salad Surgery, and the orchestra-scaled live document Pictures at an Exhibition defined arena prog's outer limits, while their 1977 tour hauling a full orchestra became a cautionary tale of the genre's excess. The classic trio dissolved in 1979 and periodically reunited before Emerson's and Lake's deaths in 2016.
ELP's signature achievement was a rock arrangement of Mussorgsky's piano suite "Pictures at an Exhibition," performed live at Newcastle City Hall with the trio's own material spliced between its movements and released as a 1971 live album; Emerson found the suite's vivid, almost cinematic imagery and stark, unresolved harmony a natural match for what he wanted a rock trio to sound like.

Before ELP, Keith Emerson led the Nice, whose radical, classically-quoting rock arrangements — like their notorious reworking of Bernstein's "America" — and suite-form pieces such as "Five Bridges" established the template Emerson carried wholesale into his next band: side-long, multi-movement music built from classical source material rather than verse-chorus songwriting.
listen forCompare the Nice's "America," with its brooding classical quotation and extended instrumental combat between organ and rhythm section, to ELP's "Tarkus" — both alternate pounding unison riffs with sudden classical-tinged calm inside one continuous, multi-part structure.
Greg Lake had just sung and played bass on King Crimson's "In the Court of the Crimson King" when he left to form ELP with Keith Emerson in 1970; accounts of the trio's earliest rehearsals describe them still working through Crimson's "21st Century Schizoid Man" alongside Nice material, and Lake carried that band's taste for abrupt tempo shifts and dissonant, mellotron-thick menace into ELP's harder-edged pieces.
