Trivium asked Richie Brown from local black metal band Mindscar to fill in on bass duties until a full-time member could be brought in.

[7] A copy of the demo was heard by German label Lifeforce which signed Trivium, and the band entered a studio to record its debut album, Ember to Inferno.

[11] Allmusic reviewer Johnny Loftus stated on Ascendancy, Trivium are a "ridiculously tight quartet, unleashing thrilling dual guitar passages and pummeling kick drum gallops as surely as they do melodic breaks and vicious throat screams.

Singles and music videos were released for "Like Light to the Flies", "Pull Harder on the Strings of Your Martyr", "A Gunshot to the Head of Trepidation", and "Dying in Your Arms".

[15] In support of the album, the band opened for Killswitch Engage, Iced Earth, Fear Factory, and Machine Head, who were one of Heafy's largest influences.

[19] In April 2006, after a headlining tour with Mendeed and God Forbid as openers, Trivium entered the studio with Suecof and Heafy producing again.

[34] While Trivium's relationship with Smith had deteriorated over the years, the band had no immediate plans to replace him when he announced in late October 2009 that he would be sitting out the 'Into the Mouth of Hell We March' tour to take care of "some personal business."

A special edition was released featuring the tracks: "Ensnare the Sun", "A Grey So Dark", "Drowning in Slow Motion", "Slave New World" cover and the single from the God of War III soundtrack "Shattering the Skies Above".

Trivium participated in a co-headlining trek with Swedish melodic death metal band In Flames in both Europe and North America.

From July 13 to August 28, 2012, Trivium took part in Metal Hammer's "Trespass America Festival" headlined by Five Finger Death Punch with additional support from Battlecross, God Forbid, Pop Evil, Emmure and Killswitch Engage.

In an interview, David Draiman revealed to Thrash Hits that the title of Trivium's forthcoming sixth album is Vengeance Falls.

[44] Vengeance Falls was produced at a studio in Austin, Texas and was mixed by Colin Richardson, who has previously worked with Fear Factory, Cannibal Corpse, Machine Head, Napalm Death, Slipknot and Bullet for My Valentine.

[45] On July 23, 2013, Trivium announced a United States headlining tour, co-headlining with DevilDriver, with supporting acts After the Burial and Sylosis, which would reveal the first information of the new album.

[49] Trivium recorded a music video for the single "Strife" with director Ramon Boutviseth (All That Remains, For Today, Fear Factory)[50] which was made available for free download to anyone who pre-ordered Vengeance Falls.

[69] To promote the album, the band announced a co-headlining North American tour with Arch Enemy in fall 2017 with While She Sleeps and Fit for an Autopsy as support acts.

[failed verification] On October 25, 2018, just over a year after the album's release, Matt Heafy announced that he had to fly home to Orlando to be with his wife for the birth of their children, and as a result, would be sitting out the remainder of Trivium's ongoing North American tour with Light the Torch and Avatar.

In Flames was originally slated as an additional opening act, but were forced to withdraw from the tour due to international visa issues caused by the pandemic, and were later replaced by Hatebreed.

[71][72] In February 2020, the band started posting cryptic images and videos possibly pertaining to their new upcoming album on their social media pages.

At the same time, the band announced their upcoming ninth studio album titled What the Dead Men Say set for release on April 24, 2020.

It is part of a split single to commemorate both bands touring together in Europe and the UK, released on January 27, 2023, on which Heaven Shall Burn covered "Pillars of Serpents" from Trivium's 2003 debut album, Ember to Inferno.

[99] Trivium's music mixes "soaring" and "crushing" riffs, dual guitar harmonies, double bass drum patterns and occasional blast beats and breakdowns that one can expect from the metalcore genre.

Trivium is one of the notable New wave of American heavy metal acts,[108] having been referred to as one of "big four" bands of the movement, along with Lamb of God, Avenged Sevenfold and Slipknot.

The Crusade was seen as a major shift in musical direction due to the change in vocal style, namely the absence of screaming, and some of the melodies featured.

Acknowledging Matt Heafy's Japanese heritage,[112] the album also was described more favorably as more their own style, as previous references to Trivium sounding like Metallica had been made on the back of The Crusade.

Trivium has also used Drop G# tuning on seven-strings on the songs 'Dead and Gone' and 'Beneath the Sun' from Silence in the Snow, 'Other Worlds' and 'The Wretchedness Inside' from The Sin and the Sentence, and 'Bleed Into Me' from What the Dead Men Say.

Trivium, and notably Matt Heafy, has stated that in general they are influenced by musical groups such as Opeth, Nevermore, Dream Theater, Emperor, Slipknot, In Flames, Arch Enemy, Machine Head, Guns N' Roses,[116] Metallica, Iron Maiden, Megadeth, Ozzy Osbourne, Mercyful Fate, Hellhammer, Celtic Frost, Slayer, Pantera, Dio, Black Sabbath, Judas Priest, Annihilator, Testament, Cannibal Corpse, Obituary, Killswitch Engage, Skid Row,[117] Angra, Martyr and Death.

Heafy also lists bands like Pantera, Slayer, Cryptopsy, Children of Bodom, Dark Tranquillity, Mercenary, Manowar, Armored Saint, Darkthrone, 3 Inches of Blood, Krisiun, Fear Factory, Dimmu Borgir, Dark Funeral, Anorexia Nervosa, Poison the Well, Hatebreed, Yngwie Malmsteen, Led Zeppelin, AC/DC, Aerosmith, Queen, Dashboard Confessional, Further Seems Forever, Depeche Mode, The Beatles, and more.

Growing up, Heafy experienced anxiety, teenage angst, and occasional thoughts of suicide; several songs from the album Ascendancy, such as "Rain", "Suffocating Sight", and "Departure", deal with these issues.

Although not a victim himself, he also wrote the song "A Gunshot to the Head of Trepidation" on the topic of domestic violence and child abuse, inspired by the stories of some of his peers.

[123] Lyrical content on The Sin and the Sentence and What the Dead Men Say were inspired by modern aspects of life, such as social media and artificial intelligence as well as general themes such as war, history and religion.
