The SXSW premiere shines a light on some of the unheralded stars of the blues scene.

Oftentimes, the best and brightest of our musical talent never get to take center stage as an adoring crowd cheers them to glory. Some of the industry's most talented players happily occupy backstage roles, studio slots or, in the case of the subjects of Scott Rosenbaum's SXSW premiere "Sidemen - Long Road to Glory," careers as sidemen.

Rosenbaum's new documentary focuses on some of American music's most skilled (and most unheralded) stars, so-called "sidemen" Pinetop Perkins, Willie "Big Eyes" Smith and Hubert Sumlin, lovingly bringing the three men's individual and collective stories to the big screen in a toe-tapping, eye-opening new feature.
