The BLUES FOR ALLAH (50TH ANNIVERSARY DELUXE EDITION) features a newly remastered version of the original album by GRAMMYr Award-winning engineer David Glasser, sourced from the original analog tapes with speed correction and tape restoration by Plangent Processes. 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." BLUES FOR ALLAH saw the Grateful Dead attempt something they never had before_and never would again. They would make the record almost entirely without pre-written material.
