Documented collaborators
The Deep Basement Shakers hail from the East Bay, California, bringing a punchy blend of barrelhouse blues, early roots, and New Orleans-inspired grooves. Core members Aaron Hammerman (piano/vocals) and Dave Eagle (washboard/percussion) define the sound, with RW Grigsby joining on select projects alongside Mark Hummel. Their raw, DIY approach blends intimate piano lines with infectious rhythm, rooted in the Bay Area’s rich blues scene.
