Hendrix played two songs at Clapton's Central Polytechnic gig in 1966, including a version oh Howlin' Wolf's "Killing Floor" that caused Clapton's jaw to drop. Somehow Hendrix managed to play lead and rhythm at the same time, with an intensity that Clapton could not believe. To Clapton, it was incredible that Hendrix could play and perform at such a high level. (From the book "Crossroads - The Life & Times Of Eric Clapton - Written by Michael Schumacher (Page 81)
