Probably the best to use the Unplugged format for exploring different sounds – bringing new listeners to music and songs they may not have otherwise heard – was Clapton.  As great as the original Layla is, I actually prefer the Unplugged version… there’s just something much more powerful with the control it brings… but here’s one that’s completely different, and a nice example for the other songs he brings to the table.  It’s mostly because of Clapton that I’ve gone out and sought after different blues artists, to at least get a familiarity.
