Tracks 1 to 7 -> very good soundboard, from radio - at Aragon Ballroom, Chicago,IL in Sep.25, 1970.
Tracks 8 to 10 -> good audience; Johnny guitar is perfectly placed up-front. His voice is almost unaudible - at Denver Pop Festival, June 1969. Despite the fair recording quality, you can considerate both recordings as "outstanding" for the period.
Notes: two albums with the name "White Lightning" can be found, the other album was recorded 1st Sep 1969.
