Daren Diolosa got the nickname Klank while touring as a guitarist in the industrial metal band Circle Of Dust after their drummer commented “He is so metal, he will klank when he hits the ground”.

In 1993, Klank submitted a stripped-down, organic demo of his song “Animosity” to REX Records (Circle Of Dust’s Christian music label at the time) and it appeared on a few of the label’s compilation releases. The up-and-coming Tooth & Nail, also a Christian label, signed him, with Klank famously signing the contract in his own blood. Though on a Christian label, Klank insisted that it was not a ‘Christian band’, despite his Christian upbringing.

Klayton (of Circle Of Dust) was recruited to co-write, produce, engineer and perform on what would become Klank’s debut album Still Suffering. The album noticeably has a much more electronic and industrial rock sound than the original demo that got him signed. To tour in support of the album, Klank called friends who were musicians and asked them to be his backing band and they hit the road for two years.

Numb followed in 1999 on the Progressive Arts Music label. The band covered all of its own costs of the album including a music video for the title track in return for a higher return on the album’s sales, but Klank shared years later that the label has never paid the band a dime for its sales and asks fans not to buy the original album or “you will be supporting a lying, cheating thief and his label”.

Klank then spent eight years working for Ringling Brothers circus as a transportation manager, show welder and steel fabricator – continuing to write music during this time, accumulating over 100 songs. After this, he began releasing music again on his own label SmokeDogg Productions. The EP In Memory Of… surfaced in 2007 at a surprise appearance at that year’s Cornerstone Festival. It was followed three years later by a re-release of Numb as Numb…Reborn with its track list as he had originally intended it to be. Urban Warfare saw release in 2012.

Rise appeared in 2017. Two instrumental albums followed including a score for the 2019 documentary Metal Health – Out of the Pit. Two volumes of Between Unholy and Divine were released in 2021/2022.
