Death Grips decided that their album was information which wanted to free, and so slapped the music up on line. Unfortunately, they'd forgotten they'd signed to Epic, and thus had no longer actual ownership of their own art.
Epic failed them, and got cross:
Epic Records’ Head of Business & Legal Affairs Heath Kudler wrote in the email, dated 1 Oct – the same day as the leak: “Epic is extremely upset and disappointed that the artist decided to release an album without Epic’s knowledge or involvement. As you know, the artist has not only blatantly breached a number of provisions in the applicable recording agreement, it also has wilfully infringed Epic’s copyright rights with respect to these masters. Equally important, without provocation, the artist has made false and disparaging statements on various websites about Epic. All this, despite the fact that Epic has done nothing except wholeheartedly supported the band, even though the band has made certain decisions that have financially damaged Epic”.Upset and disappointed. I suppose at least when they're telling off the people who made the music the RIAA companies pretend to have emotions - if it had been an ordinary person who had put up an album, they'd have actually just been got a drone strike.
Now, though Epic are going to drop the band - thereby totally alienating them from the product of their labours.
