Whatever you might think about the premise of recreating albums we've all heard a million times live--something that even the artists themselves didn't do in many cases (Beatles, eg)--set it aside and consider going to a CAL show. My son (12) was a skeptic, and was absolutely primed to hate it. By the end, he was repeating the phrase Craig hoped he would: "Dude, that was awesome."
Regardless of how many times I'VE heard Dark Side of the Moon, my preteen would never have sat through the whole thing, and this way he was exposed both to the music itself, and shared with me the experience of watching CAL recreate every sample, snort and sigh from the album, in many cases with self-consciously low-tech methods: real alarm clocks, a Foley setup with real shoes for footsteps, and spot-on noisemakers in real time for the intro to "Money."
Absolutely a great time, and worth the price of admission. Hoping they come back with some Beatles.
