Mountain Jam Mountain Jam "Mountain Jam" is an improvised instrumental jam by The Allman Brothers Band. The song's first known recording is on May 4, 1969 at Macon Central Park. "Mountain Jam" was originally released on the 1972 "Eat a Peach" album, as recorded at the Fillmore East concert hall, in March 1971 during the same sessions that produced their prior live double album "At Fillmore East". That is the rendition that is best known. Other live recordings have been released on the albums "Fillmore East, February 1970", "", "", "The Fillmore Concerts", and deluxe edition of "At Fillmore East" (1971). Notably,
Humble Pie was released to coincide with the album and failed to chart, however the band was becoming known for popular live rock shows in the US. On July 9, 1971, Humble Pie opened for Grand Funk Railroad at their historical Shea Stadium concert, an event that broke the Beatles record for fastest selling stadium concert, to that date. Also in 1971 Humble Pie released their most successful record to date "Rock On" as well as a live album recorded at the Fillmore East in New York entitled "Performance Rockin' the Fillmore". The live album reached No. 21 on the US "Billboard"
