This very rare and highly-coveted cassette sampler released in 1997 is the first recorded material from the band that eventually became Linkin Park. Known under the moniker of Xero, these recordings feature vocalist Mark Wakefield, who quit the band in the late nineties, opening the door for Chester to audition for the lead vocalist spot. Wakefield went on to become the manager for Taproot, a band who Linkin Park would end up opening for during a 2001 European tour headlined by Deftones. Every once in a blue moon, this tape surfaces on eBay and fetches offers of thousands of dollars. It is considered the ultimate item for any hardcore collector.
