Linkin Park has launched a mysterious website that seems to be related to their massively influential 2000 album Hybrid Theory. Linkin Park was seeking "photos, videos, ticket stubs, merch, flyers, souvenirs and anything else you collected from the early days of the band in the late 90’s through the Hybrid Theory era of 2000-2002," so I'm assuming this is related to that request.
Check out the website here, which looks like it's straight out of the Hybrid Theory era of the late 90s. They did a really good job recreating the feel of a computer experience from back in the day.
Hybrid Theory has been certified 11x Platinum by the Recording Industry Association of America (RIAA) since its release, having sold over 11 million copies in the United States. Hybrid Theory has also sold over 1.5 million in the United Kingdom, 4 million in Europe overall, and nearly 1 million in Germany among other countries.
