Produced by band cofounder Arthur Lee and The Doors' engineer/producer Bruce Botnick, the visionary album weaves a rich tapestry of sound as Lee's quavering voice delivers lyrics that are both enigmatic and poetic as he is backed by the band's gorgeous melodies and evocative orchestral arrangements.

Rhino celebrates the 40th anniversary of this truly essential album with a Collector's Edition of FOREVER CHANGES that contains the original 11 songs along with an alternate mix of the album comprised almost entirely of unreleased tracks. The bonus material also includes a trove of unreleased gems culled from the album's recording sessions. The two-disc set will be available April 22 in stores and at www.rhino.com

Recorded during the Summer of Love in Hollywood, CA, the album is the group's most fully realized studio effort, featuring Lee (vocals, guitar), John Echols (lead guitar), Bryan MacLean (rhythm guitar, vocals), Ken Forssi (bass) and Michael Stuart (drums, percussion). The original album includes the classic "Andmoreagain," plus the Lee-penned tracks "Red Telephone," "A House Is Not A Motel" and "Live And Let Live," as well as "Alone Again Or" and "Old Man" written by MacLean.

Disc 2 contains an unreleased alternate mix of all but one of the original tracks. (The alternate mix of the album closer, "You Set The Scene," first appeared on Rhino's 2001 reissue of the album.) The disc's ten bonus songs feature six unreleased tracks including an original mix for the album outtake "Wonder People (I Do Wonder)," an alternate electric backing track for "Andmoreagain," tracking session highlights for "The Red Telephone" and an outtake of "Wooly Bully." The previously released bonus cuts include "Your Mind And We Belong Together," the b-side "Laughing Stock" and a demo version of "Hummingbirds," a song that would later become "The Good Humor Man He Sees Everything Like This."
