A$AP Rocky and Tyler, the Creator are both on major labels, but their roots are firmly in underground and alternative hip-hop. The ability of both artists to bring their 2015 tour to Red Rocks with like-minded artists Danny Brown and Vince Staples may not have signaled a major change in the world of hip-hop, but their elaborate set designs were on par with what you might see at any large-scale concert, short of those by monster acts like Nine Inch Nails, Radiohead or Miley Cyrus. It felt as though experimental hip-hop had finally arrived.
