Its 1st cloth publication was in '54. It was 1st published in paper in '58.

Mission of Gravity was nominated for a Retro Hugo Award for '54.For a profit & adventure Barlennan would sail thousands of miles across uncharted waters, into regions where gravity played strange tricks. He'd dare the perils of strange tribes & stranger creatures--even dicker with those aliens from beyond the skies, though the concept of another world was unknown to the inhabitants of the planet of Mesklin. But in spite of the incredible technology of the strangers & without regard for their enormous size, Barlennan had the notion of turning the deal to an unsuspected advantage for himself--a considerable enterprise for a being very much resembling a 15" caterpillar!

    His only companions are the disembodied voice of Miranda Taligent, the only woman he has ever loved, and the cryogenically frozen body of her father Prospero, the genius and industrial magnate who drove her insane.The tale of Harold’s life is also one of an alternate reality, a lucid waking dream in which the well-heeled have mechanical men for servants, where the realms of fairy tales can be built from scratch, where replicas of deserted islands exist within skyscrapers.. As Harold’s childhood infatuation with Miranda changes over twenty years to love and then to obsession, the visionary inventions of her father also change Harold’s entire world, transforming it from a place of music and miracles to one of machines and noise. And as Harold heads toward a last desperate confrontation with Prospero to save Miranda’s life, he finds himself an unwitting participant in the creation of the greatest invention of them all: the perpetual motion machine.Beautifully written, stunningly imagined, and wickedly funny, The Dream of Perpetual Motion is a heartfelt meditation on the place of love in a world dominated by technology.

    When the warped citizens of Europe proclaim Colin Charteris their hero, he finds himself leading an unfathomable crusade in a devastated world. Perhaps Aldiss's most experimental work, this first appeared in several parts as the 'Acid Head War' series in New Worlds. Set in a Europe some years after a flare-up in the Middle East led to Europe being attacked with bombs releasing huge quantities of long-lived hallucinogenic drugs. Into an England with a population barely maintaining a grip on reality comes a young Serb, who himself starts coming under the influence of the ambient aerosols & finds himself leading a messianic crusade. The narration & dialog reflects the shattering of language under the influence of the drugs, in mutating phrases & puns & allusions, in a deliberate echo of Finnegans Wake.--Wikipedia
