Eric Clapton’s Crossroads Guitar Festival kicked off on Friday at Dallas’ American Airlines Center with performances from the host guitar legend plus fellow axe icons Jeff Beck, Sonny Landreth, Jimmie Vaughan and Peter Frampton, along with Bonnie Raitt, Sheryl Crow, Keb’ Mo’, Marcus King Band, Doyle Bramhall II, Gary Clark Jr., Citizen Cope and more. One of the evening’s highlights came when welcomed Clapton for a fiery take on The Beatles’ “While My Guitar Gently Weeps,” which Clapton famously guested on during the “White Album” sessions.

Announcing the sit in, Frampton addressed the crowd, saying that playing with Clapton has “been a dream of mine for many, many years—decades…I’m going to invite out a friend—I’ve known him a long time, but we’ve never played together.”

The two guitar virtuosos filled the cover with plenty of solo heroics, trading licks back and forth during the extended take. Watch a video of the collaboration here:

As Clapton fan site Where’s Eric! reports, after Landreth opened up the musical festivities last night, Clapton offered a short acoustic set with a backing band of Andy Fairweather Low, Jamie Oldaker, Steve Gadd, Nathan East and Pedrito Martinez. The collective opened their set with “Circus” and ran through a cover of Jimmy Cox’s “Nobody Knows You When You’re Down and Out” plus Clapton classics “Tears in Heaven,” “Wonderful Tonight” and “Lay Down Sally.” Watch a full video of the set here:
