By any measure, 1970 was a high-water mark for the Grateful Dead. Hot on the heels of the incredible success of Workingmans Dead that summer, the band returned in the autumn with the equally stunning American Beauty. Those back-to-back classics not only introduced songs that would be a key part of the groups live repertoire for decades, but they also opened a gateway into the world of the Grateful Dead for generations of Dead Heads. American Beauty celebrate its 50th anniversary this year with two new releases.
