With rumors that Linkin Park has multiples celebrations planned to honor Hybrid Theory‘s 20th anniversary, the band surprised fans by streaming a previously unreleased track from 1999 called “She Couldn’t.”

Linkin Park also announced that a 20th-anniversary reissue of their smash debut, Hybrid Theory, will arrive on October 9th, in either a 5-CD set or set with three LPs.

A super-deluxe reissue set is coming, too, with live concert DVDs, an 80-page illustrated book and lithographs from members of the band.
