Out today is the Doors' 50th anniversary edition of their fourth album, The Soft Parade. The new set has been issued as a triple-CD and one-LP set featuring nearly two hours of unreleased recordings -- including the premiere of the entire "Rock Is Dead" jam. The Soft Parade, the only extensively orchestrated Doors collection, was originally released on July 18th, 1969 and peaked at Number Six on the Billboard 200 albums chart.

The album featured four singles -- the Robby Krieger-written Top Three hit "Touch Me," which had been released the previous December; "Wishful Sinful," which stalled at Number 44 -- although it hit Number Three in Denmark; the album's lead cut "Tell All The People," which only reached Number 57; and "Runnin' Blue," which topped out at Number 64 on the Billboard Hot 100.

According to the press release for the new set:

Among the highlights are stripped down "Doors Only" versions of five tracks where the horns and strings have been removed -- "Tell All The People," "Touch Me," "Wishful Sinful," "Runnin' Blue," and "Who Scared You." The set also features three of those stripped-back versions with new guitar parts added by Robby Krieger for "Touch Me," "Wishful Sinful," and "Runnin' Blue."

The collection also uncovers three songs from studio rehearsals -- with Ray Manzarek on vocals -- that include an early version of "Roadhouse Blues," a song that would be released the following year on Morrison Hotel.

These three songs include newly recorded bass parts by Robert DeLeo of Stone Temple Pilots, who joined Krieger and John Densmore at a tribute concert for Manzarek in 2016, three years after the organist died of cancer.

John Densmore told us that from the beginning to the end of the band, the Doors had a chemistry unparalleled: "Ray and I were completely synchronistic in our musical sensibilities. We just. . . intuitive stuff together and backed up Robby's soaring solos and Jim's vocal and. . . we were blessed. We gotta remember that was the muse coming in. Y'know, she just visits when she wants to. Yeah, even with Jim's self destruction, every time we made an album, when we were behind closed doors, there was a sacredness to the four of us."

Robbie Krieger says that looking back, the Doors' short time together was relatively free of ego problems or star trips: "It was really, like, the perfect group, y'know, as far as working together and stuff. There was no ego problems, y'know, and petty jealousies and stuff like that that a lot of groups go through."
