I'm grateful that YouTube suggested Tedeschi Trucks Band - Bonnaroo 2014 (https://www.youtube.com/watch?v=UpwzuXlutY8). There is early Derek Trucks solo where Susan smiles at him. Although I can't claim any insight, she could be in a transcendent state: appreciating his technical mastery, enjoying the music, and marvelling that she's married to the guy.
How many can have that experience (especially being backed by two drummers, a pair of backup singers, and a horn section)?
