Pink Floyd-"Atom Heart Mother" (1970)

For many this album was the beginning of the end of the psychedelic era of Pink Floyd, for others a transition album that was quite despised by fans, (and even by the band itself), and is that the absence of Syd Barrett still weighed heavily like a slab and partly undermined the ideas of the group members.
Even so, the group leaves us a huge suite, the one that gives the album its title and that becomes one of the philosopher's stones of progressive rock.
Special mention is the work to the engineering controls of a huge Alan Parsons that achieves a glorious sound, with all the instruments playing in their entirety.
In "Fat Old Sun" you could already sense where the band would go when David Gilmour composed, and in "Alan's Psychedelic Breakfast" we find the Pink Floyd who sounded a few years later with a superb piece, where Wright and Gilmour they are amazing, with a sublime sound, and that made it clear where the paths of the "new" Pink Floyd would go.
The album was a huge success in the United States and the United Kingdom as well as many other countries, achieving sales that far exceeded one million copies.
