The music that would ultimately become the "Hybrid Theory" album was first produced by Linkin Park in 1999 as a nine-track demo tape. The band sent this tape to various recording companies and played forty-two different showcases for recording industry representatives, including performances for Los Angeles promoter and impresario, Mike Galaxy's showcase at The Gig on Melrose. However, they were initially turned down by most of the major labels and several independent record labels. The band was signed by Warner Bros. Records in 1999, due in large part to the constant recommendations of Jeff Blue, who had joined the label after resigning from Zomba.
