Geoff Muldaur delivered some of his best work joining forces with other musicians—namely Paul Butterfield, Maria Muldaur and Amos Garrett in the ’70s—but the most important and longest collaboration began with Jim Kweskin in the mid-’60s when their formative group Jim Kweskin Jug Band fused folk, jazz and blues into their own brand of acoustic music. Kweskin and Muldaur began playing together again in 2012. The duo revisited their roots with the recently released record Penny’s Farm.
