One critic called it the greatest live rock solo ever and he was referring to Eric Clapton's guitar solo during a performance of Crossroads by Cream at San Francisco's Winterland Ballroom in March of 1968. Cream's original version of the song had bassist Jack Bruce handling the vocals but in this version it was Clapton front and center.
Clapton, Bruce and drummer Ginger Baker formed Cream in 1966. Clapton had left the Yardbirds following the recording of "For Your Love" because he felt the band was forgoing it's blues roots in favour of a more commercial approach.
Cream issued four albums in it's short 2 year life - Fresh Cream, Disraeli Gears, Wheels of Fire and Goodbye. Clapton went on to form Blind Faith with Steve Winwood, Rick Grech and Ginger Baker.
