Even though this video has been viewed almost 18 million times—it still strikes me as something of a rare bird (probably because I've—somehow—never seen it before!).
The clip, which apparently was shot in January 1986, shows Stevie Ray Vaughan and Double Trouble running through three songs—"Scuttle Buttin'," "Ain't Gone 'n' Give Up On Love" and "Say What!"—during a soundcheck at an unspecified venue.
According to the info posted with the video, it shows "Stevie just waking up, then warming up."
Assuming this is true, it's annoyingly insane how incredible SRV could be at the drop of a hat—or at the ring of a bedside alarm clock. It's particularly impressive how he digs into "Ain't Gone 'n' Give Up On Love," meaning he was truly "feeling it" that day. It's also sort of priceless to see Vaughan, Tommy Shannon, Chris Layton and Reese Wynans just sort of milling about before and after takes.
