"The set also features almost two hours of unreleased recordings. Among the highlights are rehearsals from the band’s August 12, 1975, soundcheck at San Francisco’s Great American Music Hall, including the album tracks “Sage & Spirit,” “Help On The Way,” “Slipknot!,” and “Franklin’s Tower.” The collection continues with performances from the June 21, 1976, show at the Tower Theatre in Pennsylvania, spotlighting five BLUES FOR ALLAH songs alongside favorites like “Eyes Of The World.” Rounding out the set are selections from Bill Graham’s SNACK (Students Need Athletics, Culture, and Kicks) Benefit at Kezar Stadium on March 23, 1975. Previously only available on the 2004 Beyond Description box set’s Bonus Disc, the recordings include one of only three known performances of “King Solomon’s Marbles.”"
