Despite the fact that most critics hate them... I honestly don't. Looking at them as just a "rap group", they are definitely mediocre, members Violent J and Shaggy 2 dope are typically simple, lyrically. Often using A-B
rhyme schemes, I don't think they are incompetent about it or anything, I'm pretty sure the simplicity is a choice, because I've actually heard Violent J rap some decent bars.(With some really questionable lyrics, however) ICP do not take themselves seriously. You can almost call them a pastiche on hip hop.
Example being, while most rappers would brag about owning cars, having sex with attractive women, and
other typical exploits, ICP will boast about stuff that no sane person would ever brag about,(IE having sex with women who are described as repulsively unattractive) or have it be cartoonishly over the top.
Shock value stuff. ICP decidedly isn't about being real. Instead they usually tell horror stories, and often they "play" the part of the killers in these songs. While I do like this idea, it's hard to make these kind of songs for as long as they have been, and honestly, there hasn't been an ICP album that I really enjoyed since 1997's The Great Milenko. They still make decent tracks every now and then, but for the most part, I think that they are kind of beating a dead horse at this point. But most of their fanbase still enjoy the new albums, so all power to them, I suppose.
But, honestly, he provides very eclectic and unique instrumentals. Ranging from relaxing, chill beats, (see Ninja, Out) to more intense beats (Chicken Huntin', How Many Times).
