So, this just happened -- GWAR: Tiny Desk Concert

Amazing dude. I loved the part at the end when they ate all the NPR correspondents and pooped their corpses into Hell

HAHAHAHAHA that's amazing.

If you haven't seen it, their appearance on The Onion's Under Cover series (with Oderus RIP) was amazing.

Please explain... Who is GWAR? What is Tiny Desk? What's going on??

Identified by their distinctively grotesque costumes, Gwar's core thematic and visual concept revolves around an elaborate science fiction-themed mythology which portrays the band members as barbaric interplanetary warriors, a narrative which serves as the basis for all of the band's albums, live shows and media. With over-the-top violent, sexual, and scatological humor typically incorporating social and political satire, Gwar has attracted both acclaim and controversy for its music and stage shows, the latter of which notoriously showcase enactments of graphic violence that result in the audience being sprayed with fake blood, urine, and semen. Such stagecraft regularly leads Gwar to be labeled a "shock rock" band by the media.

Tiny Desk Concerts is a video series of live concerts hosted by NPR Music at the desk of All Songs Considered host Bob Boilen in Washington, D.C.

Magic.
- Not sure why you wrote it as quotes, but thank you for writing such a comprehensive answer to my questions. You truly are like magic, as you with no regard for humility, noted. The context given in the post was severely lacking.
GWAR is a less-than-serious thrash metal band

Tiny Desk is a long-running series in which musicians (usually indie rock, but it has included all sorts over the years) are invited to do a stripped down set at, well, a tiny desk. There are a lot seriously high-quality performances in their archives, but GWAR... don't quite fit the usual theme
