The 50’s and 60’s gave us a lot of delta blues dressed up, first as rock and roll, then as blues rock. No surprise that Cream applied that treatment – brilliantly, in my books - to I’m So Glad by Skip James.
So if you’re a contemporary of Cream, you go looking for another tune, right? I mean, what’s the point in re-doing See See Rider after the Animals? No wait, someone did. Actually, lots of people. Nevermind.
Anyway, it turned out if you were Deep Purple you could re-do I’m So Glad and make it totally new. You know, just weave Rimsky-Korsakov’s Scheherezade around it. Obvious!
Not really, and that’s what made that psychedelic era so freakin’ amazing. Thanks to the fearless, restless exploration that dominated the times, a simple little ditty became a psychedelic, early prog rock tour de force.
