It’s all about the harmonica at Blues Vespers this Sunday. Immanuel Presbyterian‘s monthly free blues service features award-winning Seattle player Paul Green as the headline act in its 8th annual Harmonica Showcase, along with Stacey Jones and Steve Bailey. Tom Boyle and the T-Town Aces rhythm section will back up the stars, plus there’ll be a guest appearance by London blues star Tim Aves.

“The harmonica provides a second voice connected directly to the feeling of the player,” says Green about his instrument, also called the mouth harp or Mississippi saxophone.

The Blues Vespers is a blues concert with poetry and a short reflection by Rev. Dave Brown.
