The first word that comes to mind with this, in fact most of Gary Clark Junior's performances, is "authentic".
Although I'm not usually one to draw comparisons, on this occasion I will. Gary Clark has the air of the real thing, compared to say Joe Bonamassa. Sorry Joe. More melodic, less histrionic, and very reminiscent at times of a guy called Jimi.
Hailing from one of music's hot spots, Austin, Texas, and blessed with the perhaps unfortunate nom de plume "The Chosen One", Gary Clark has always been his own man and while not shunning the limelight, he doesn't seem to seek it out either.
It was the connection with renowned Austin club Antone's manager Clifford Antone which set Clark on the path to recognition and his eventual major-label debut in 2012. Now 33, Gary Clark seems to have been round longer than that, such has been his impact in the five short years since.
