"Cars Hiss by My Window" is a slow, atmospheric blues from The Doors' 1971 album L.A. Woman, performed in a 12-bar blues form in E at a languorous 72 BPM. The track is one of the album's most intimate and stripped-down performances, evoking late-night solitude through Morrison's understated vocal delivery and imagery of urban isolation. Robby Krieger contributes an electric guitar solo over one full blues chorus, employing slide guitar techniques that give the performance a distinctly Delta blues quality rarely heard in the band's earlier work. Jim Morrison also takes an improvised vocal solo later in the track, scatting and moaning through the blues changes in a raw, unscripted passage that showcases his deeper roots as a blues vocalist. The song reflects the influence of the band's surroundings during the recording sessions, set up in their workshop space on Santa Monica Boulevard where the sounds of Los Angeles traffic could occasionally be heard bleeding through. Manzarek's restrained keyboard accompaniment and Densmore's brushwork create a hushed backdrop that lets the blues form breathe. The dual solo approach, pairing Krieger's guitar with Morrison's spontaneous vocal improvisation, illustrates the creative freedom the band found by self-producing the album outside the constraints of a formal studio environment.
