Seth Walker sings in a decorous voice that sheds its Sunday best as it heats up, and he plays blues guitar in the manner of Snooks Eaglin and other New Orleans masters. The North Carolina native cut his teeth in the competitive Austin, Tex., blues scene, where his impeccable taste and economical licks brought him attention. You could compare Walker to retro-soul musician James Hunter, but Walker possesses a modest yet intense vocal style all his own. On his 2006 full-length release Seth Walker, the singer essayed Dave Bartholomew and Pearl King’s classic New Orleans tune “By the Water” and made the song sound as if it were written yesterday. Walker has continued to record, and his ear for great material remains unflagging. If modern blues means dragging Nick Lowe, Tom Waits and Percy Mayfield into the same room to share a bottle, Walker is sure enough the blues.
