Bobby Weir Shares Unreleased “Peggy-O” with John Mayer and Matt Berninger

A previously unreleased live recording of the Grateful Dead classic “Peggy-O,” performed by Bobby Weir, arrives today ahead of Bobby’s Blue Mountain 10th Anniversary Deluxe Edition due November 20 via Rhino/WMG. Recorded at Los Angeles’ Wiltern Theatre on October 10, 2016, the performance hails from Bobby’s extensive tour in support of his acclaimed 2016 solo album Blue Mountain. Listen to/share the song HERE.

The track features Bobby on vocals and acoustic guitar, Matt Berninger on vocals, Steve Kimock and John Mayer on electric guitar, Josh Kaufman on the Wurlitzer electric piano, Scott Devendorf on bass, Bryan Devendorf on drums and Jon Shaw on the mandolin.

The live recording is part of the ongoing celebration of Blue Mountain’s 10th Anniversary, which includes the expanded deluxe edition featuring further previously unreleased recordings, live performances and more. Pre-save the Deluxe Edition HERE.

The Digital Deluxe Edition features unreleased recordings from the Blue Mountain studio sessions and live performances from Bobby’s fall 2016 “Campfire Tour.” The previously unreleased studio material and live performances give a fuller picture of Blue Mountain, from the making of the album to the songs as Bobby brought them to audiences on the road.

The newest track comes on the heels of the previously unreleased studio recording “The Ground Don’t Want Me,” which offers a rare glimpse into the creative process behind one of Bobby’s most personal and distinctive projects. The song was recorded during the original Blue Mountain sessions—but never released—and provides another window into the musical world Bobby explored on the album, drawing on the storytelling traditions, wide-open landscapes and enduring spirit of the American West.

Originally released September 30, 2016, Blue Mountain marked Bobby’s first album of entirely original material in more than 30 years. Co-produced by Bobby Weir and Josh Kaufman (Bonny Light Horseman), the album features songwriting collaborations with Josh Ritter and performances from The National’s Aaron Dessner, Bryce Dessner and Scott Devendorf. The album drew inspiration in part from the traditional cowboy songs Bobby first encountered as a teenager working on a ranch in Wyoming, music and stories that stayed with him throughout his life and ultimately found their way onto Blue Mountain.

Recorded at locations on both coasts during the spring and fall of 2015, Blue Mountain brought Bobby together with a wide-ranging group of musicians and was engineered by Dan Goodwin. Across songs including “Only a River,” “Gonesville,” “Lay My Lily Down” and the title track, Bobby explored the landscapes, characters and traditions of the American West through a collection unlike anything else in his catalog.

“Having the chance to work intimately with Bobby Weir on his album Blue Mountain was a dream for me. He was so open throughout the process, and his collaborative spirit was on full display at every session and with every musician we brought into the fold,” details Kaufman. “Working on this 10 year anniversary edition has really brought me back to that feeling…Here’s to you Ace! Thanks for the adventures and the music.”

Following the release of Blue Mountain, Bobby took the album on the road for the “Campfire Tour,” bringing the new songs to the stage alongside music from across his career. Joining Bobby were Bryan Devendorf, Scott Devendorf, Josh Kaufman (Bonny Light Horseman), Steve Kimock and Jon Shaw, with several guests appearing along the way including Aaron Dessner for a portion of the fall leg and entirety of spring. Recordings from the tour form the live portion of the Deluxe Edition, including “Stuck Inside of Mobile with the Memphis Blues Again,” capturing the music of Blue Mountain as Bobby brought it to the stage.

Blue Mountain was Bobby’s first solo studio album since 1978’s Heaven Help the Fool and his first studio album since recording Evening Moods as the leader of RatDog in 2000. The album was met with widespread critical acclaim upon its release, with critics singling out its songwriting, understated performances and deeply rooted take on the American West.
