Nine Inch Nails

After frontman Trent Reznor railed against record labels in 2007, calling them "thieves," the band released an entire album for free online months before it was to be released on CC and vinyl.

The album, "The Slip," was made available for download on the band's website, accompanied by a statement from Reznor that said, "Thank you for your continued and loyal support over the years - this one's on me."
