Sage can't remember much about living in Austin, but she remembers Dallas, where Jimmy Vaughan's daughter Tina came to visit while their dads jammed into the night years before the Fabulous Thunderbirds and Stevie Ray Vaughan were household words. She remembers Los Angeles, with its musical days and nights. Then there was Boulder, then Northwest Arkansas. Always, there was music. Bramhall frankly can't imagine life without it, though its pursuit has a classic simplicity in his mind.
Music is melody-driven.
You just follow it to chord progression. Translate it to the instrument. The lyrics come naturally. Maybe it's easy for a man who moves freely from piano to guitar to harmonica. Maybe it's genetic.
