An Industrial Metal out of Finland forged during 1997. PAINFLOW's first demo would secure a deal with the German Massacre label. The band's debut album would be recorded in Hagen, Germany with producer Siggi Bemm. However, unsatisfied with the mix the group returned to Finland getting Mikko Karmila to conduct a remix.

Just as the album was completed guitarist and programmer Jarkko Mäki unexpectedly commited suicide. Beset by this tragedy the band took time to consider whether to continue or not, eventually resolving to forge ahead with Ville Janatuinen taking over guitar. The 'Audio Visual Aids' record would be finally released during July of 1999, issued with differing cover art in their home country by Spinefarm Records.

Following live work PAINFLOW enrolled new drummer Lauri Bexar and Pekka Hackspick replaced Arjo Mennstrom on guitar. After a further run of shows in Finland the group splintered in two with Ville Janatuinen, bassist Mika Hotakainen departing. Adding new guitarist Rami Kaartamo and severing ties with Massacre Records PAINFLOW morphed into GOD'S AN INSECT during 2002. The band at this juncture cited a roll call of vocalist Aki Viljamaa, guitarists Pekka Hackspik and Rami Kaartamo and drummer Lauri Bexar.

Painflow is currently known as ZERO INDUSTRY and is unsigned.
