YES! These are two of the best Grateful Dead albums ever. They contain other treasures too, such as "Uncle John's Band" (my favorite), "Ripple", "Trucking" (their big hit), "Casey Jones" ("Driving that train, high on cocaine...") and "Sugar Magnolia".

"Live Dead", a double album that came out just before these two, is probably their best live album. It has a 23 minute version of "Dark Star" that is exquisite and a song, "The Eleven" that is played in 11/16 timing (1-2-3-1-2-3-1-2-3-1-2).
