The album is divided into a front side dedicated entirely to the suite composed collectively by the band supported by Ron Geesin and a side where we find three songs written respectively by Waters, Wright and Gilmour and last long track collectively, "Alan's Psychedelic Breakfast". This "democratic" track list recalls the studio album "Ummagumma".
Atom Heart Mother
(Father's Shout) The simple and epic overture of the suite, apparently of total paternity of Ron Geesin, is based on the brass section on where they fit even rumble of motorcycles.
(Breast Milky). It is one of the most beautiful movements of the suite, characterized by the famous dialogue between the organ and cello arpeggio, simple but beautiful grounds. On this delicate tissue finally starts the guitar of Gilmour. The guitarist appears around the album particularly inspired and very calibrated in parts. After an orchestral crescendo, the quiet is back.
(Mother Fore). Come on stage the chorus of which shows immediately the remarkable quality. In this movement, alternating moments of high drama and some passages actually a bit boring but the overall result is still fascinating. The impetuous intro of Mason's battery remains a beautiful moment of dialogue between modern and classic sound.
(Funky Dung). It is probably the most successful part of the entire suite. Bass and organ work in counterpoint and upon these starts Gilmour, who performs one of the best solos of his career. But the tension grows further with the addition of voices of onomatopoeic chorus, which interact with the vibrant and powerful organ. Here we are at one of the zenith of rock history. The tension dissolves with wind instruments, liberators, reproduce the opening theme.
(Mind Your Throats Please). On a muddy keyboard sounds, evocations, rumors, according to the tradition of the band, showing in particular the vagaries of humorous "A Saucerful of Secrets" and "Echoes".
(Remergence). From disintegration and chaos the remergence the overture and then the duet between cello and organ. The final is impressive, with a guitar always incisive and with the orchestra and the choirs that punctuate the musical crescendo.
A simple guitar arpeggio, a soft voice whispering words full of melancholy poetry, dreamy guitar in a short musical interludes. This is "If", rightly considered as one of the sweetest songs of Pink Floyd.
It is the contribution of a Wright peak of his, sometimes modest, creativity. If it is true that certain passages seem too pompous for the intervention of the orchestra.
"Summer '68" is simply a successful hymn to the joy of living, the evocation of a love story, a flashback on the unique moments and emotions that can leave us a fleeting summer meeting.
Fat Old Sun
The warm and subtle voice of Gilmour and dreamy atmosphere, almost bucolic, make this song a classic of Pink Floyd production and in line with the production of early years (for example, "Green Is The Colour" from the soundtrack "More" of 1969). The guitar solo closes the song.
