"This is the first authorised release of these four historic complete 1968 concerts. Each concert features previously unreleased tracks and the Royal Albert Hall show hasn’t featured on CD until now.
This historic collection was produced by Bill Levenson. The Oakland Coliseum, Los Angeles Forum and San Diego Sports Arena concerts were mastered from the original 1968 analog mix reels by Kevin Reeves at Universal Mastering, Nashville, TN. The Royal Albert Hall concert was mastered from the original 1968 analog transfer reels by Jason NeSmith at Chase Park Transduction, Athens, GA.
The set features 36 tracks of which 29 are issued for the first time."
