Lost Demos is a collection of fourteen demos and works in progress by American band Linkin Park, recorded around the sessions for their album Meteora. The material was released in 2023 as part of Meteora's twentieth-anniversary edition. The recordings present songs at an early stage, with the band's trademark blend of nu-metal, rap and electronic elements and the dual vocals of Chester Bennington and Mike Shinoda. Notable tracks include "Lost", "Fighting Myself" and "More the Victim". The collection offers insight into the band's creative process during that period.
