Wednesday Bluegrass at Cooper Mountain Aleworks Tigard! The Jamblers play a blend of country, folk, bluegrass, classic rock, jazz, alt-indie, standards, originals & more – then jamble ’em together into our acoustic-style sound. Some call it “Americana,” others “Variety.” We just call it “Music,” the kind everyone can enjoy. Presented in partnership with the Oregon Bluegrass Association. All ages, no cover.
