Alien Force is a heavy metal band from Denmark. The band formed in 1982 by two brothers, Henrik (guitars) and Michael (drums) Rasmussen. They were then joined by Peter Andersen (Vocals) and Michael Østerfelt (bass). The group released one single under this name and in 1984 the band changed its name to Alien Force. The band released two LPs, Hell and High Water and Pain and Pleasure both of which are considered a classic in the NWOBHM underground.

The band then went through disagreements and replacements and the band fell apart. They wouldn’t play together until 2008 in a reunion concert, and then not again until 2018 at another concert. The band has recently released their comeback album We Meet Again and the band is still active.

The bands main inspiration is Judas Priest.
