The "Rolling Stone Album Guide" called "In Memory of Elizabeth Reed" in its original studio incarnation "the blueprint of a concert warhorse, capturing the Allmans at their most adventurous." "The New York Times" has written that "its written riffs and jazz-ish harmonies improvisers room." Accordingly, "Elizabeth Reed" has appeared in many Allman Brothers concerts, sometimes running half an hour or more, and on numerous Allman Brothers live albums, but first and most notably on "At Fillmore East", which many fans and critics believe is the definitive rendition. In 2007, "Rolling Stone" named "In Memory of Elizabeth Reed" one of its Fifty Best Songs Over Seven Minutes Long – and in giving it Honorable Mention on its 100 Greatest Guitar Songs of All Time list made 2008, "Rolling Stone" called the "At Fillmore East" performance "transcendent".
