"Atom Heart Mother Suite" is a six-part epic by prog rock band Pink Floyd, composed by the whole band(Roger Waters, David Gilmour, Richard Wright, and Nick Mason) and Ron Geesin. It appeared on their Atom Heart Mother album in 1970, taking up a whole side of the record. It is Pink Floyd's longest un-split epic, clocking in at 23 minutes and 51 seconds, beating "Echoes" by about 17 seconds. It is also the only Pink Floyd song over 15 minutes long without lyrics. Though very few consider the "Suite" their favorite song, it is a hardcore-fan favorite, with the likes of "Green Is The Colour" and "Wots...Uh The Deal?", from More and Obscured By Clouds respectively. It is rumored to have been played in one take, with a very unsteady tempo.
A. Fathers Shout
Opening with a low keyboard note, a brass section swoops in, creating a dramatic effect. The brass and drums play for a minute or two, before the music calms down into a cello and organ solo. A quiet guitar section plays before launching into a screaming guitar solo.
B. Breast Milky
Picking up directly after the last note of the guitar solo, this is a five-minute choir piece, backed by Wright's organ and, a few minutes later, Mason's drums.
C. Mother Fore
A simple band jam session, somewhat similar to the one on "Echoes". This also contains the second, and less powerful, guitar solo, which quietens into an interesting chanting piece by the choir. The song then slowly builds to another brass and drums section.
D. Funky Dung
The first of the two 'noise' pieces of the song, this is essentially a lot of high-pitched noises. A distorted voice says "Here is a loud announcement!" about 10 seconds before the next section starts.
E. Mind Your Throats Please
This is another 'noise' piece, but uses various instruments fading in and out (many of which are recognisable from earlier in the suite). An unsteady brass rhythm plays, and the distorted voice from Funky Dung is heard yelling "Silence in the studio!" before exploding into yet another brass and drums section, which then quietens into...
F. Remergence
A reprise of the cello solo, followed by the first guitar solo being played with even more screeching guitar. This all leads into a climatic ending with everything playing, and the choir singing, ending with a very long note from the choir and brass.
