Still remember headbanging hypnotically to Townsends "Grace" about 13 years ago. Metal has always been my main emotional catharsis.

I've always found moshing to be a primal dance, and felt some of my most inner confidence at metal shows.

Now in my mid 30s, starting to see some of my old idols pass -- from Alexi Laiho, Brent Hinds, and Ozzy, it's been rough

Yep, as a metal head who loves to play along to his favorite songs, this is the next frontier I want!

Moises is able to do that! Though it's unfortunately not open source. Result quality can vary as with anything AI, but ime it usually performs ok.

How many track/stem pairs would we need to train a network to do this? Must be possible now with llms
