band demos (which too appears on the Immersion box set). The song features the only keyboard solo on The Wall by Richard Wright (although on live performances, "Young Lust" and "Another Brick in the Wall, Part 2" would also feature keyboard solos); after the last line of lyrics, a synthesizer solo is played over the verse sequence, in place of vocals. Following the solo, the arrangement "empties out" and becomes sparse, with the guitar only playing an ostinato with rhythmic echoes, and brief variations every other bar. Sound effects are used to create a sense of paranoia, with the sound of cruel laughter, running footsteps, car tyres skidding, and a loud scream. The original 7" single version and Pink Floyd The Wall -- Special Radio Construction promotional EP both contain a clean guitar intro, without the live crowd effects. The EP version also contains an extended, 32-beat intro and an extended 64-beat outro where David Gilmour's main guitar phrase repeats before the track ends. As with "Comfortably Numb", also from The Wall, the music to "Run Like Hell" has its roots in Gilmour's first solo album. "Short and Sweet" can be seen as this song's precursor. "Yes," Gilmour told Musician magazine, "it's a guitar with the bottom string tuned down to a D, and thrashing around on the chord shapes over a D root. Which is the same in both [songs]. [Smiling] It's part of my musical repertoire, yes." Composition After the previous song, "In The Flesh", the crowd continues to chant, "Pink! Floyd! Pink! Floyd!" The guitar intro begins with the scratching of strings dampened with left-hand muting, before settling on an open D string dampened by palm muting. As heard earlier on the album in "Another Brick in the Wall, Part 1", the muted D is treated with a specific delay setting, providing three to four loud but gradually decaying repeats, one dotted-eighth note apart, with the result that simply playing quarter notes (at 116 beats per minute) will produce a strict rhythm of one eighth note followed by two sixteenth notes, with rhythmic echoes overlapping. Over this pedal tone of D, Gilmour plays descending triads in D major (mostly D, A, and G), down to the open chord position (a quieter, second overdubbed guitar plays open chords only). Some of the guitar tracks are also treated with a heavy flanging effect. The verses are in E minor,
