"Mountain Jam" is an improvised instrumental jam by The Allman Brothers Band, based on Donovan's 1967 hit song "There Is a Mountain". The first known recording of a performance was done on May 4, 1969 at Macon Central Park. "Mountain Jam" was originally released in 1972 on the album "Eat a Peach", 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"). It is this rendition that is best known.
