[1] At the end of 2017, the band had already recorded instrumental demos for their EP No One Should Read This[1] and within six days Bonitz had written lyrics and self-recorded vocals for each track.

[11][12] On July 18, 2019, the band played a show at The Lizard Lounge in Lancaster, Pennsylvania, during which Bonitz climbed onto the ceiling of the venue.

[13][14] The band released a music video for the song "Red Light" on January 21, 2020, and announced that they were entering the studio with Josh Schroeder.

[15] In 2019, the band parted ways with Eric, and in 2020, they went to the studio as a four-piece, with Alizé "Mewzen" Rodriguez tagging along as their unofficial DJ.

[28] Tallah released a live shot concert on October 1, 2020, in which they played their debut album Matriphagy from front to back.

[29][30] In 2020, Alizé "Mewzen" Rodriguez joined as the band's DJ,[31] and they also debuted their new rhythm guitarist, Alex Snowden from Doll Skin.

[33][34] On August 17, 2021, they released the single and music video "Vanilla Paste", featuring guest vocals from Grant Hood of Guerilla Warfare, AJ Channer of Fire From the Gods, and Tom Barber of Chelsea Grin.

[note 1] John D. Buchanan of AllMusic described Tallah as a "nu-core" quartet...[that brings] back the spirit of early-2000s nu-metal with gnarly riffs, whipcrack drums, electronic textures, and tortured vocals.

[1] According to Next Mosh, "[Tallah's music includes]...screaming vocals [mixed] with melodic choruses and driving bass guitar with deep and dirty tones, syncing up effortlessly with the thunderous bellow of drums and the screeching ping of the snare.

"[65] Phillip Trapp of Revolver described their second album, The Generation of Danger, as "a ferocious fusion of early Slipknot intensity — spitfire vocals and grooves that dig deep...and modern hardcore savagery à la Vein.fm and Knocked Loose.

"[58] Vocalist Justin Bonitz cites Slipknot, Linkin Park, Korn, System of a Down, Code Orange, Fire from the Gods, and Knocked Loose as his influences.

[5] The band's debut album, Matriphagy, is about a "man who is trapped in a house, under the thumb of his mother, and begins to lose his mind and touch insanity as he scrambles to escape.

The album touches on oppression, society’s social engineering, nature vs. nurture, metaphysics, and all kinds of psychological themes.
