"Playing the Foole in Wonderland" was recorded during the 1975 Gentle Giant tour. That same year the "Official Playing the Fool Live" was recorded and edited.
This recording (of great sound quality) shows Gentle Giant at the peak of their energy level on stage. They were so special that it is not crazy to say that possibly there will never be another band like this in popular music. Their playing skills in concert belong to the classical enviroment, not to rock and Roll. But they also knew that pure virtuosism wasn't enough, that having fun while playing was important too. That's why they always left room for creativity, playfullness and improvisation, specially in those songs with long instrumental interludes like So Sincere. You'll also listen to another unforgetable xylophone solo by Mr. Kerry Minnear in "Funny ways".
I never got to see them live but listening to bootlegs and watching old videos one can guess that every Gentle Giant concert was a very unique experience. I feel sad everytime I realize that this is not a band whose members will ever reunite again. Pity. Earth could be a better place if they do.
Note added later (thanks faugn for this information)
This is the same as Playing The Foole, but with an additional track, March of the Trolls, written and played by another band. Allegedly, it was the high school band of the person who issued the record, out of his parents' house in Orange County near Los Angeles.
