Jimi Hendrix

So this gentleman released, in just two years ('67-'68), these three albums: "Are You Experienced?", "Axis: Bold as Love", and "Electric Ladyland", at least two of which are among the 10 most beautiful rock albums of all time. That alone would be enough for a forever 5. Moreover, this man is THE GUITAR, the absolute and pure essence of this instrument. Timeless.
