Originally known as Combat, the Thrash trio Napalm secured a record deal with Combat Records' (no relation, but the label forced them to change their name to Napalm). Their first release was a self-titled EP under the line-up of Chris Weidner (vocals/bass), Jeff Rossbach (guitar) and Rex Rossbach (drums) in 1986, printed as a part of Combat's' Bootcamp series. The EP was an energetic bust of Thrash and one of the better sellers of the series, but despite already having a long-term deal with Combat' (the label), the band and label couldn't agree on the futureand the original lineup folded.
When Wiedner recruited a new group in the form of Chris Weidner (bass/vocals), Chris Liggio (guitar/vocals), Jeff Lombardi (guitar) and Robert Proimos (drums) Combat' wasn't interested anymore and nullified the contract, and so SPV' picked them up to release their first full-length album, Cruel Tranquility (1989). Wiedner himself was ousted from the band shortly thereafter with Brett Roth taking over his bass duties, and by the time of 1990s Zero To Black their style was less Thrash and more Power Metal based; this album proving to be the least representative of their style. Though the band subsequently closed up, the Rossbach brothers (two-thirds of the original lineup) are still active in the music business, having resurrected the old Combat name and occasionally play in the New York area.
Footnote: Their Napalm EP was re-released in 1999 with the Have Mercy/Powermad EPs.
