Watch the Avalon online guitar lesson by Brooks Robertson from Essentials: Boom-Chick Fingerstyle Etudes
Once again, it's always a good idea to first watch and listen to the performance video a few times to help become more familiar with the tune, form, phrasing, etc. Remember as you watch, focus your attention to what the right hand is doing, then rewind and watch again, this time focusing on what's happening with the left hand. Use this video as a resource to frequently reference and eventually to play along with as well. Don't forget to utilize the tabs, charts, and notation.
