Side one "Tom Sawyer" features a backbeat in a
time signature, along with instrumental and closing sections in . It was the first Rush recording for which Lee used his 1972
Fender Jazz Bass, which provided a punchier lower end than he had been able to obtain with his usual
Rickenbacker 4001. The bass became Lee's primary studio instrument from the recording of
Counterparts (1993) onward. Lee said the group had more trouble with "Tom Sawyer" than any other song on
Moving Pictures, and at times had doubts as to whether it would work. The band had technical difficulties with the computer that mixed the tracks, so they decided to operate the mixing desk manually with each member handling their own set of faders. Lee described the tale as "
Orwellian in nature", which deals with an individual taking their Barchetta on a fast ride despite the banning of high speeds and is chased after by hovering patrol cars for breaking the law. It stemmed from the band's enjoyment of recording "
La Villa Strangiato", a nine-minute instrumental on
Hemispheres (1978); it was something they wanted to do again for
Moving Pictures, only shorter. The opening of the track features an audio clip of a busy Metropolis city from
Richard Donner's
Superman (1978). The main riff was written by cover designer
Hugh Syme on a synthesizer and double-tracked drums in one verse. "Witch Hunt" would become a part of the
Fear series of songs, which includes "The Weapon" from
Signals (1982), "The Enemy Within" from
Grace Under Pressure (1984), and "Freeze" from
Vapor Trails (2002), and appeared in reverse chronological album order, except for "Freeze" which is the fourth part and did indeed appear fourth. "
Vital Signs" was the last song that the band wrote for the album, which was pieced together at Le Studio. It features a sequencer part produced by an
Oberheim OB-X synthesizer, and shows a distinct reggae flavour. Reggae influences in Rush's music were first heard on
Permanent Waves, and would later be heard more extensively on their next two albums. == Artwork ==
