Coditany of Timeness Two technologists trained a neural network to produce a black metal album.

They started with a pre-existing recording, cut it into tiny tracks, then taught the software to arrange the clips into convincing music. Here's their paper.
This album is part of a submission to NIPS 2017 Workshop for Machine Learning, Creativity and Design: "Generating Black Metal and Math Rock".

This album was generated with a recurrent neural network trained on raw audio from the album "Diotima" by Krallice. All titles were generated by a Markov chain. The album cover was created with neural style transfer.

The copyright issues are interesting. To what extent is the output of a neural network trained on X a derived work of X? How large an amalgamation of works does X have to be before each is diluted to the point where copyright is extinguished?

In all seriousness, it is as Nelson says above: Lou Reed's "Metal Machine Music" absolutely to a T. You have to laugh, somehow. Lou Reed -- damn!

I had the same thought as everyone else here. Eventually some drums do kick in and make it sound a little more black metal though.

People are still better at that.

Serious question. What's the difference between neural network machine learning and Markov chains?

Yes. The Rammstein clip was far far better.

Tagged as "deathmetal"? Ooooh...heads are gonna roll. Or, more to the point, churches gonna burn.

What's the difference between neural network machine learning and Markov chains?

At some 50,000 foot level they're similar but they are completely different mathematical models. Neural networks have more complicated functions embedded in them and often more complex structures. The theory is they can learn to do more phenomena more accurately and learn them faster. More reading here and here.
