Frank Tedesco, pianist / musician meets people on Omegle, takes song requests and plays them - and for ones he doesn't know, he listens once on his phone then plays them by ear.

Billy Wilkins, guitar and vocals, https://www.youtube.com/@BillyWilkins
The Doo, guitar and piana and otamatone, https://www.youtube.com/@TheDooo
Both Frank Tedesco and Marcus Veltri frequently did joint Omegle videos with Rob Landis. Tedesco and Veltri also have some joint videos. I seem to also recall some Wilkins, Landis, and Tedesco collaborations.
edit: i'm not exactly musically inclined. When i was in college the joke was Guitar Center had painted a line around the building in the parking lot and i was not allowed to cross it.
