Videos:
Emmure - 10 Signs You Should Leave features a woman tied to a chair and tape gagged. Fun fact, other than the singer everyone who performed the song in this vid is no longer with the band.
Chelsea Grin - Recreant also has a girl bound and gagged by two assholes who get their comeuppance. Bit of gore in this one as well as a lot of shaky cam cause that was cool. (STEP THE FUCK BACK)
Chelsea Grin - Hostage Has lots of footage of a woman bound. Wonder if someone in the band is into bondage... (I THINK I'M GONNA DIE HERE)
World End Man - Whore Mutilation has a woman bound to a chair with her mouth sewn shut and is totally nonplussed about it.
We The Kings - Say You Like Me Something way more lighthearted. This fun video game themed video is all about saving the girl who is bound and cleaved gagged.
Girls Aloud - I think We're Alone Now (tied up ending) Exactly what is says in the title.
Empire - S.O.S has all members chained to cars wearing face guards in a very Mad Max inspired video. Don't worry, this video is way more lighthearted than it sounds

Huntress - Eight of Sword has the lead singer, Jill Janus, bound and blindfolded, the other band members are blindfolded for good measure. Rest in peace, Jill.
Kishidan - Kira Kira has one girl (maybe? she's really androgynous) handcuffed. There's also a dominatrix in the video with one member of the band very happy about his opponent, I would be too if I was in his shoes.
Art:
Ghost Bath - Moonlover (warning - nudity). The cover is a woman bound, gagged, and blindfolded with rope wearing a moon helmet. The moonwoman has become something of a mascot for the band, and it was on some of their merch when they dropped the album and they shared people having the moonwoman tattooed on them on their Facebook page.
Necromidol - scions of the blasted health Has two women bound and about to sacrificed? The girl in front seems pretty chill about it. The band also did this photoshoot, which was the inspiration for this thread. The rope work was done by someone who clearly knows what they're doing when it comes to rope art.
Merch
Infant Annihilator - the Crucifucked shirt (WARNING CORE) offend everyone with this shirt!
That's all I can think off the top of my head. If I think of other examples of DID in music I'll update this post.
