Austin's Gary Clark Jr. says his musical career began when he was 12 -- a mentor pushed the guitar towards him, and next thing he knew, he was playing on stage with blues legends like harmonica hero Walter Higgs. Eventually Clark ditched high school classes for six-string practice. In this edition of In My Room, a collaboration between Hive and Yours Truly that brings musicians into intimate settings, Clark Jr. shows off his years of practice on his songs "Bright Lights" and "When My Train Pulls In." Watch him effortlessly glide over those strings -- we can't help but think that Higgs is beaming with pride. Hey, even Clark's high school teachers are probably smiling.
