What about some good old rapcore / rap metal stuff?
Bionic Jive - Swarm - pretty strange reunion in 2018 for music video for a song from 2001 album.
Insolence - Poison Well - just a track from one of my favorite albums of all time. Back in the days, Insolence was a band that motivated me to learn to play the electric guitar. It's all because of rumors that this album (Revolution) was recorded without any real instruments, except for guitar. Yeah, almost all of my friends were metalheads and nobody wanted to play something with a "rap" in the title. :D
Resorte - Alcohol - vocals by Pato Machete (from Control Machete). I can't remember where I found this band, but I was surprised when I saw a music video.
StillWell - Mr. Yellow #5 - not exactly a rapcore and not as old as the previous three, but vocals by Q-Unique. Definitely a "diamond in the ruff".
