Well its Tuesday and every day that starts with the letter ‘T’ is a mandatory thrash metal day. So, jumping on the self created trend we present to you Long Island, NY thrashers EXTINCTION A.D.‘s all new music video, “Secret Worlds“, taken from their upcoming second full length album, ‘Decimation Treaty‘. The video shows the quartet thrashing their guts out in a small studio kind of room belting out pure, unadulterated, nerve wrecking and high speed thrash metal of intense demeanor. This is the first music video we’ve seen off the band’s fast approaching new LP due release this Friday, out via Good Fight Music. Prior to this the band has unveiled two more singles of the very same upcoming album.
