There's several acts out there that ended up incorporating a BDSM performance art angle into their stage shows back in the 1990s, particularly on the industrial scene. Some of these were clearly doing this either to cover for a lack of interesting music, or merely adopted it as a cool, edgy aesthetic, but on their debut album the Genitorturers combine an apparent passion for the subject matter with pretty solid tunes and performances.
The core of the band is married couple Gen and David Vincent. At this point in time, this was a side project for David, since his main gig was in Morbid Angel - but it's Gen who takes on frontwoman duties and brings this vicious, almost gutteral edge to her vocals. Lots of 1990s metal groups were going for a "beauty and the beast" aesthetic where the female vocalist was meant to sound as pretty as possible and leave anything remotely harsh to her male counterparts; Gen doesn't get into outright death metal growls here, but she does give the impression of being a woman you absolutely do not want to cross, defiantly roaring about sexual subject matter with a disarming frankness which really helps the overall aesthetic.
As far as the backing goes - it's 1990s industrial metal of a fairly commercially-leaning sort. It's a few notches more metallic than what the likes of, say, Marilyn Manson were putting out at the time, but it ends up at a point where it manages to be extreme without being enormously innovative. If you're quite into the 1990s industrial metal style and think Gen's vocals are enjoyable and the lyrical subject matter appeals, 120 Days of Genitorture will seem like a grand old time, but it's never going to be seen as the most truly groundbreaking and experimental of industrial metal efforts.
