There are more than one band named Machines.

The first, formed around December 2006, and are a rock 'n' roll-influenced hardcore punk band featuring members of RX Bandits, No Motiv and The Warriors. While so far only an unsigned side-project with no releases to their name, demos have been released through their website for download.

The second formed in 1977 by guitarist Nick Paul they played The Roxy and Vortex in the twilight of those venues popularity and even blew The Damned off stage one gig at the City Of London Polytechnic. In all fairness though The Machines were not major league players, but they had the spirit and drive, like so many, for one maybe two singles.

The 3rd group called the Machines" is a Belgian melodic pop-group formed in the beginning of the 80's. They won the Humo's rock rally in 1980.
