Experiencing Hendrix

We've been listening to Jimi a lot lately; wondering how someone who's been gone 40 years can still hold that much sway over us.
And then we came across Chris Richards' Washington Post review of Jimi's Valleys of Neptune album [Experience Hendrix/Legacy-2010],
a recent offering of mostly unreleased material. In it Richards states:

"Why does this stuff still sound so good? Hendrix can no longer shock us with kaleidoscopic garb or onstage bravado, but his music still manages to violate our expectations with a subtlety that feels like magic."

Yeah...
