Recorded live at American University on Sunday December 13, 1970, at 7:30 and 10:30 p.m. (The CD is drawn from both shows) the Allmans were at a crucial stage in their development on that December night, having just returned from shows at the Fillmore East in New York on a tour promoting their second album, Idlewild South. Three months hence, they would return to the Fillmore East and perform the show captured on their epochal Live at Fillmore East album. So, the band playing at American University is near to the best the group could be. The playing is fierce, especially the interaction of Duane Allman and Dickey Betts, with a solid 20-plus-minute version of "Whippin' Post".
