Generous doses of Blind Faith and Derek & the Dominos music, some jaw-dropping collaborations and more solos than Chicago has hot dog stands made Eric Clapton's second Crossroads Guitar Festival a hit yesterday (July 28). The 11-hour concert was held before a sell-out crowd of 28,000 at Toyota Park in the Windy City suburb of Bridgeview and featured Clapton, B.B. King, Jeff Beck, John Mayer, Vince Gill and Buddy Guy, among others.
