Chuck Berry somehow delivered the most thrilling set of a show that included Alice Cooper's infamous 'chicken' moment, featured crowds waving lighters and matches for the first time, was financed by a notorious motorcycle gang, marked Yoko Ono and John Lennon's first performance together, and saw ticket sales soar from 2,000 to over 20,000 in less than four days. This recording captures Berry's performance from what was arguably 1969's most exciting and underappreciated festival and perhaps his best of all time.
