Strange Days is the Doors' second album, released on September 25, 1967 on Elektra Records, just nine months after their debut. Produced by Paul A. Rothchild, the album was one of the first rock records to make extensive use of the newly available eight-track recording technology, allowing more layered arrangements than the debut. The band's core lineup — Jim Morrison on vocals, Ray Manzarek on keyboards, Robby Krieger on guitar, and John Densmore on drums — is supplemented by session bassist Doug Lubahn, who provides bass guitar on several tracks. "When the Music's Over" closes the album as an eleven-minute suite in the mold of "The End" from the debut, moving through quiet passages and explosive climaxes. "Love Me Two Times" and "People Are Strange" were released as singles, with the latter becoming one of the band's most recognizable songs. Manzarek plays harpsichord on several tracks, adding a baroque texture to pieces like "You're Lost Little Girl." Krieger's guitar work continues to draw on blues, flamenco, and jazz influences. The album reached number three on the Billboard 200 but sold less than the debut, partly because the band's four songwriters had used their strongest pre-existing material on the first record.
