Those Were the Days is an ambitious four-disc, 63-track box set that divides Cream's career into two halves. The first two discs feature every studio track the group ever released, plus a handful of unreleased cuts, alternate takes, and rarities. The other two discs are devoted to live material, which is segued together in an attempt to recreate the "ideal" Cream concert. It's a remarkably comprehensive collection, complete with an extensive booklet and remastered sound, yet it doesn't reveal any new insights about Cream, nor does it offer any invaluable rarities. Therefore, it's only for die-hard collectors or listeners wanting to acquire the entire Cream catalog at once; casual fans will be satisfied with individual albums or greatest-hits collections.
