This is one of the most famous blues/rock licks of all time. Played by Dwayne Allman from the Allman brothers and not Eric Clapton, this lick kicks off one of the most epic tunes ever.

Played in D minor, the lick to Layla perfectly outlines the 5th, b7th, root and b3rd. Watching the bends on both the 13th and 15th frets, they should be full bends that release fully as well. The basic lick simply loops around, but try adding your own little flavor.
