According to this:

- The story of I Am Legend[1954] is highly unlikely, yet Matheson [the author] uses his tacit understanding of human nature to craft a psychologically realistic protagonist. It is striking that in the face of fierce attacks from the walking undead,
Neville listens to music, puts works of art on his walls, and watches motion pictures on his home projector. As an author, Matheson no doubt intuitively understands the deep psychological need for art that probably everybody experiences: art is a human
universal, essential to human nature. 22 After a particularly violent attack on his house, Neville sets about fixing the broken generator and, significantly, putting up a mural on his living room wall, and then, when the work is done, sits down to listen
to Mozart
