There are at least 5 bands called Trial:

1) Hardcore band from Seattle, Washington, United States. Since forming in 1994 the band has worked desperately to communicate their infusion of activism, emotion, anger and intensity in a world where people are more comfortable remaining sedate. Challenging that attitude, Trial has never given up, all the while fueled by a relentless desire to play hardcore music which is charged with political and personal fury.

2) A peace punk / post-punk band from San Francisco, featuring Cyrnai (ex-Treason/Sleeping Dogs/State of Mind). They released one 7" ("Inborn System") and one LP entitled "Moments of Collapse" in 1986.

3) A german EBM band from Hannover active since 1991.

4) A traditional Metal band from Belgium. Pretty rare but truly West-Euro Metal in its most pure and gloriously blackened form.

5) A Swedish heavy metal band. They released their first album "The Primordial Temple" in 2012. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
