Defiatory was formed in Umeå, Sweden, in 2015 and quickly adapted the roots of the East Bay Area thrash metal scene. With their straight and heavy riffs their sound takes you from early Megadeth, Exodus, Metallica to a more modern style of thrash.
After the departure from Aeon, Ronnie started up Defiatory in early 2015. Soon after, Martin Runnzell joined the band to fill the vocal spot. Martin's voice character was just perfect for this purpose and within a week the band had created their first demo called ”Furor Unleashed”.
After releasing the Furor Unleashed demo, Jon Skäre joined up to fill the drum position.
A new demo was recorded at Garageland Studios during the summer of 2015 called ”Aeons End”. A three song demo that started the whole writing of the debut album.
In August Defiatory started to write songs for what was going to be their debut album and after recruiting lead guitarist Ludvig Johansson(Apostasy, Mesolimbic) and bassplayer Patrik Wall (Apostasy, Crowdburn) the band was complete.
Defiatory made their first official live performance at House Of Metal on March 4th 2016, opening the 10th anniversary of the festival.
The debut album entitled "EXTINCT", a ruthless 38 minutes of thrash metal laid out over 8 songs, was recorded at Garageland Studios in Umeå, produced, recorded and mixed by Ronnie Björnström and mastered by Thomas Johansson at The Panic Room. It was released on June 3rd 2016 on Black Lion Productions.
