Several bands go by the name The Plague:

1) 1960's garageband from the US, known for the song 'face of time'.

2) 1970's Art/Rock band from New Zealand:

In 1977 Richard von Sturmer returned from England, according to The Mechanics Of Popular Music "charged with the new punk movement that flourished there. He assembled a troupe of 'actors' and they rehearsed a series of theatre/music pieces revolving around his poetry and showmanship. The called themselves The Plague." They used material from Inside Information; songs such as Frank Gill's An Idiot and Private Property.

3) 1980's Gothic/Death-Rock Band from New York, recorded "Naraka".

"They have a dark sound with quite an edge to it. Singer Margot Day has a voice that a lot of people would say has a kind of a Banshees/4AD sound, but has style all her own. Margot also plays the flute, this adds a nice touch to a few of the songs. . ." --Geddy

4) Modern Death-Metal Band that now goes by the name "This Ending"

5) Dutch death-metal band: Founded under the name "Strangled", which was soon changed to "The Plague". After some line-up changes The Plague is now ready to conquer.
