In 2018, the album was remastered and rereleased by the Owsley Stanley Foundation, with the title Bear's Sonic Journals: Fillmore East, February 1970. There are two different versions of this release. One contains the same material as the original album. The other is the Deluxe Edition, on three CDs, with two discs containing all the music that was captured on tape at the concerts.[1][2]
Fillmore East, February 1970 is composed of selections from those concerts. The album was produced by Stanley, who also wrote the liner notes. It was mastered by the Dead's recording engineer, Jeffrey Norman. It was released on the Grateful Dead label, in cooperation with the Allman Brothers' record company at the time, PolyGram Records.
Performances by the Grateful Dead from the same set of shows have been released on two albums – Bear's Choice, and Dick's Picks Volume 4.
On AllMusic, Lindsay Planer wrote, "There is no mistaking the unbridled fervor of the original line-up of the band. Rising to the challenge of exploratory psychedelia – while remaining ever faithful to their Southern blues roots... Likewise, the Allman Brothers were beginning to ascend as not only premier interpreters, but purveyors of a revolutionary new electric guitar-driven blues movement".[4]
In The Music Box, John Metzger said, "... the disc opens with a scorching rendition of "In Memory of Elizabeth Reed" that simply grooves. Dickey Betts and Duane Allman are magnificent, as they play with reckless abandon, yet tightly in synch. The highlight of this album, however, is the nearly 31-minute "Mountain Jam" that drips with a colorfully electrified intensity."[5]
In Glide Magazine, Doug Collette wrote, "Almost a year after the formation of the seminal Southern rock band... the original sextet was homing in on the sound that would lend itself to At Fillmore East, the epic recordings done thirteen months later at the same venue. Yet even as the group... was honing the influential style that would make them famous, they were stretching themselves as well, shuffling novel and well-established material in and out of their repertoire."[7]
Doug Collette of All About Jazz commented: "At its most dramatic peaks, the Allman Brothers Band's collective musicianship was nigh-on miraculous to behold and never more so than with its original personnel. As the septet approached the first anniversary of their formation, the accelerated process of their growth supplies only more evidence to that end."[3]
Note: "Discs 2 & 3 contain the sonic journal reels of the three shows as recorded each night, unaltered. Portions from these three chapters were used to create the compilation album (disc 1)."
