Heavy, filthy and satanic thrash metal would be the best way to describe British thrash legends Onslaught and their debut album, Power From Hell. Originally a punk band, Onslaught retained some punk elements when they changed styles to thrash and that is evident in the driving, punk-style rhythms on their debut although not so much in their later albums. Drawing influence from other extreme metal acts of the time such as Possessed, Slayer and Venom, Onslaughts riff work on this album is gritty, fast and thrashy, simple but effective. You can hear the bass a little in most tracks but it mostly follows the guitars all the way through the album, so nothing special there. The production on the album isn't great but I think it adds a little to the dark and dense atmosphere. Power From Hell is probably best listened to on vinyl if you're lucky enough to find a copy but it still sounds good digitally.

A lot of the lyrics on this album are satanic, again, much like early Possessed and Slayer. Paul Mahoney's vocals on this album are nothing really special, pretty standard thrash vocals for the time but they fit well with the music, especially the heavy riff-work. I think the band definitely made the right choice when they hired Sy Keeler to handle the vocal duties on The Force (Killing Peace and The Sounds Of Violence too).
Overall Impression — 8
Power From Hell is heavier than most albums being produced by other early thrash bands of the day, an essential cult classic for any thrash fan. Stand-out tracks on the album for me are "Damnation/Onslaught(Poer From Hell)", the mid-paced "Lord of Evil", the crushing track "Death Metal" and "Thermo-Nuclear Devastation". If it were stolen or lost I would probably by it again but I'd try hunt down a vinyl copy first before getting another CD. A solid piece of heavy as hell old-school thrash metal.
