Classic British psychedelica - which clearly indicates that some of the lesser known (but still important Cream milestones) are also included. The heavy hitters are also included and the liner notes are interesting. This is a history lesson. I enjoy listening to this era, because I remember this era. Cream may have been groundbreaking, but other outfits were also in contention (i.e. Hendrix, Doors, Stones, Beatles) so the the competition was stiff. That said, one has to realize that this music was introduced during a period when recording engineering was really just coming out of its infancy (when compared to the tools in use today). So, some of the tracks (the early ones) have a cheesy sound. Beatle records of this same period had a much better sound quality due to the fact that the Beatles (corp) was dumping a lot of money into state of the art equipment on which to record... Sgt Peppers was recorded on what... 4 or 8 tracks and THAT was a HUGE step forward technologically. All in all this is a good compilation/retrospect that documents Cream. In that regard it has value. I guess one could say, it's a groovy record... and it did take me back... I started thinking about other groups like Vanilla Fudge, Big Brother, Quicksilver Messenger Service, Moby Grape, and was wondering if it all sound this dated (and yes it did!) oh there were some groups which weighed in heavy, groundbreaking, perhaps the Experience (Hendrix), Cream, Doors but British psychedelica was different than the American version, in some respects a little tamer with only a few exceptions (Hendrix and Cream), the rest of the British scene were hold over "invasion" bands --gettin' heavy-- back then it didn't seem that way, but in retrospect that's what the musical legacy has left the listener with. It was another time, pop bands got groovy and a few newcomers came onto their own or evolved into different groups with much more to say. You have to appreciate that when giving this a listen.
