Black Sheep Hit: The folk-inclined "From the Beginning" is the band's sole Top 40 hit in the United States. Similarly, the folky ballad "Lucky Man" became a moderate hit in Canada and the Netherlands and climbed up to #48 in the USA.
Creator Killer: Works started their decline, but Love Beach was the final nail in their coffin. To be fair, they only made it because they owed their label another album and were already planning on disbanding anyway.
H. R. Giger: Did two paintings for Brain Salad Surgery.
Throw It In: "Lucky Man" - the synth solo was recorded in one single take, which is something that Emerson's been embarassed about. Also, Palmer's Ringo-esque exclamation "They've only got ham or cheese!" at the end of "Are You Ready Eddy?".
In fact, the story of "Lucky Man" makes the whole of the song a Throw It In: the band were one song short of the label's quota on the last day of recording. Lake proceeded to play the ballad he wrote when he was 12, which nobody else was very receptive to but he reminded them they needed one more song. Emerson told him to record it himself and went off to the pub. Lake and Palmer took a first try at the song, and the result was, by their own admission, awful. Lacking any alternatives, Lake overdubbed a bassline onto the song, which suddenly improved it. He then proceeded to overdub more guitars, the choir-like vocal harmonies and an electric guitar solo, with the result being, in his own words, "it sounded pretty good... it sounded like a record". Emerson chose this time to return from the pub and listened to the song, being surprised at how it had gone from a piss-take to being an actual song, and he commented "Wow, I suppose I better play on that!". Lake reminded him the song already had a guitar solo, to which Emerson instead suggested he play over the conclusion, and that he use his recently acquired Moog synthesizer that he hadn't had the chance to test before. Thus, Emerson fetched his Moog synth, asked engineer Eddy Offord to run the tape "as an experiment", and recorded the ending solo in one take.
According to Keith Emerson in the book "Pictures of an Exhibitionist", a pun on Pictures At An Exhibition, this was a not-entirely-true rumor. The way he described it, when he and Greg Lake were looking for a drummer, they at one point considered Mitch Mitchell (formerly of the Jimi Hendrix Experience), who mentioned to them "Maybe I could get Jimi interested in joining", but that's as far as it went. Jimi was apparently supposed to try jamming with them, but he died first.
