"Alan's Psychedelic Breakfast" is the fifth and final track from the 1970 Pink Floyd album Atom Heart Mother, credited to the whole group.
[4] In addition to the talking, the sounds of Alan making breakfast—such as lighting the stove, cooking bacon, pouring milk and cereal (which makes a popping sound associated with Kellogg's Rice Krispies), loudly gulping and drinking, and loudly and vigorously eating cereal—are clearly audible in the background,[4] which adds a conceptual feel to the track.
[4] On some copies of the vinyl version, the dripping tap at the end of the song is cut into the run-off groove, so it plays on infinitely until the listener removes the stylus from the album.
[8] In his 1997 History of Progressive Rock, Paul Stump assessed the morning sounds as "nothing more than a reportage of events" with no meaningful integration into the piece's musical language.
He also remarked that as an experiment into the use of noise as music, "Alan's Psychedelic Breakfast" does nothing that composers such as Morton Subotnick, John Cage, and Karlheinz Stockhausen had not done before.
[10] In another review for the Atom Heart Mother album, Irving Tan of Sputnikmusic described the track as an 'incredibly effective form of "wallpaper music'".
[11] In 2018, Ultimate Classic Rock contributor Bryan Wawzenek ranked the piece among Pink Floyd's worst songs, deeming it to be a "13-minute slab of musique concrete fulfills a request that (probably) no Floyd fan ever made: 'What does roadie Alan Styles like for breakfast, can we hear him making it and could the guys in the band noodle around (in a very non-psychedelic manner) as he fries bacon, muses about marmalade and pours a bowl of Rice Krispies?'.
