Goose Creek Symphony: Est. 1970 (1970)
Beyond the pleasant acoustic guitar jangle and fiddle, you've got some lovely harmonies throughout (like on the brief opener, a gospel/Beach Boys hybrid, and the gorgeous closing hymn "Symphony Music"), and some impressive electric guitar jams as well. "Charlie's Tune" is silly Appalachian fun; "Big Time Saturday Night" is Dead-friendly harmony-rich country-rock; "A Satisfied Mind" is simply lovely and reminds me of the early Nick Lowe/Brinsley Schwarz pub rock take on Americana. Elsewhere, the sprawling "Talk About Goose Creek" combines rustic jaw harp with a blazing jam, while "Beautiful Bertha" is a Band-like electric stomp.
Give it a shot, you might be surprised.
