Hendrix figures in the Jackson Street jazz story more by association and lineage than by any direct participation in the jazz scene, but Seattle’s blues- and beat-based music definitely affected his development. Hendrix’s father, Al, was a noted jitterbugger and his mother worked as a teenager in a Jackson Street club known as the “Bucket of blood.” Like so many Jackson Street jazzers, he attended Garfield High School (though he flunked out), and grew up musically in the gritty, blues-influenced milieu of the “Northwest rock” sound developed the Wailers and others. Hendrix played with one of his first bands, the Velvetones, at Birdland, where Billy Tolles had started the Savoy Boys, and at Washington Hall, with the Rocking Kings.
