"The Metro" was System of a Down's first cover, performed in 1995 on their Untitled 1995 Demo Tape. This version of the song was slowed to a crawl and had a dark moody sense of playing.
Re-recorded by the band for their Demo Tape 4 in 1997, it became less moody and truer to the Berlin original, as the tempo was increased.
A third version was sped up greatly and Daron Malakian lent his vocals in parts, appearing on System of a Down's "Lonely Day" maxi single as "Metro". .
