Agony

Here are more bands named Agony:

1.) Agony, originally formed as Agoni in August 1984, was a swedish thrash metal band. Their first demo-tape titled "The Future Is Ours" was released in March 1986. A tour in Britain with swedish punkers Anti-Cimex, and a second demo-recording ("Execution of Mankind") followed the same year, before changing name to Agony.
In 1987, the band obtained a record deal with the famous Music For Nations label, and released their full-length debut album, "The First Defiance", in 1988. The music was similar to the early works of bands such as Exodus, Metallica and especially Testament. Sadly, it would also prove to be their last effort, as the band disbanded shortly afterwards.

2.) Current death-doom metal band from Dacice, Czech Republic

3.) Ambient/Doom Solo project of Nick Vossen (ex-Arkngthand) from the Netherlands is also called Agony
