There ar two bands using this name:

1) Device was the brainchild of 80's songwriter wunderkind Holly Knight. Knight was a prolific songwriter in the 80's, penning hits for Pat Benatar ("Love Is A Battlefield", "Invincible"), Animotion ("Obsession", "I Engineer"), Tina Turner ("Better Be Good To Me", "The Best"), Aerosmith ("Rag Doll") and Scandal ("The Warrior".)

Ironically enough, Paul Engemann- the lead singer for Device, went on to be one of the lead vocalists for Animotion. (He sang co‑lead with Cynthia Rhodes on their «Room To Move» hit.)

Device's one and only album, the cryptically titled «22B3» would be the group's only release but featured a bonafide eighties greatie in «Hanging On A Heart Attack.» It was a Top 40 hit in the U.S. and was in heavy rotation on MTV. The follow‑up single «Who Says» didn't garner the same attention, but its video still gets some airplay on Vh‑1 Classic.

2) Device is latvian band formed in year 1998 in Liepāja. Band members: Marats Ogļezņevs (Marathons) and Ruslans Kuksinovičs (Rus‑L). Device first single is called « Find A Point». They are playing Hip‑Hop and R'n'B.
