Stevie Ray Vaughan was 29 by the time break-out Texas Flood was released. Hed been a working musician for over a decade by then, setting fretboards and blues clubs alight throughout Austin; as recalled here by a (largely very Texan) cast of old bandmates and blues connoisseurs.
Yes he found fame in the 80s, but a LOT happened before then as this relatively academic but engaging documentary reminds us. At least as significant here, however, is Stevies place in the wider blues movement of the time from crackly Blind Lemon Jefferson recordings, to wonderful footage of the young Johnny Winter.
A flash of gleaming stetsons, shiny jackets and bigger stages speedily depicts his spotlight years, in stark contrast with the minutiae in which his formative influences and local scene are explored. For a broader audience, a wider-reaching documentary would strike more of a chord. As a hefty shot of Texas blues history, however, this is a solid investment.
